guys the situation is this:
i'm in the club,i stopped a girl and i'm talking to her or another situation i'm dancing with her
the girl seem to like me and things are going good but.........suddenly a friend of her(i'm talking about friends who are girls) came,grab the girl and take her away.
this is shit man!!!!!!!
all my efforts are gone for a stupid friend.
i swear that i'm talking about situations in wich the girl gave me signals that like me.
i hate these friends
i don't know how to behave
be angry with the friend is pointless but i need a good tactics....i can't throw away many opportunity because of a stupid friend
(we should also reflect about girls behaviour.....if i'm dancing with a girl and a friend of mine grab me and pull me away i'll hit him.girls instead let her friends do and often i see in their eyes that they are not happy about this)
what would you do guys in a situation like that?

well i been meaning to try this, lets say they grab her and take her away they do this cause of jealousy and well you would have to act quickly and get the number right their and then and say that her friend is rude for barging in unannounced, two things can happen 1 say i am sorry or something and this has happend to me before and more often the what the fuck do you want lookif its the latter treat the obstacle as she treats you treat her friend like gold if you want my opinon still need more field practice to see if it works

If I were in your situation, I would have just looked at the girl I was talking to, smirked, and said something like, "Hey! Don't be so rude. Introduce me to your friend". Try to control the situation. I find it's always best to address or notice the new person in the set first so you are taking the lead. You are saying, "Introduce me!" and everyone else is playing into that scenario now. If you extend yourself out to the new person, chances are they may be more open to meeting you or following your lead since you took charge.

Chances are, her friend is "saving" her from you or the situation for whatever reason.. it may not even be you as a person. Maybe the girl you were talking to is really drunk, she has a boyfriend but disregards that when she parties, her friends are leaving but don't want to leave her behind, etc. It could be like an, "I'm so sorry she's bothering you. She's really drunk and we're taking her home" type deal. It's not because of anything you did and it's not personal, it's because her friends are looking out for her and don't want her to be in any situations which can't be controlled.

as roberto64 said a way is try to take the number as soon as possible and i have already done that when was possible.
vegas said that a good thing to do is try to be introduced to her friends and this make sense but......
the situation that i was talking about is when you have just met the girl.....i mean you met the girl since a minute.
i'm talking about the dancefloor.the girl is dancing,i go close to her and start to dance.my hands are already grabbing her hands and we are dancing close but i didn't have the time to say nothing neiter my name or anythng else.her friend come grab her and pull her in a very rough way and with strenght and both walk away
what should i do then?
no time to be introduce to her friends
we also should reflect more about this thing to be introduced to her friends.i agree with vegas that in some situations can be a good idea but often also happen that girlfriends are envy(and if we are speacking about guys friends is much worse) and they could do everything possible to make you go away.
so sometimes trying to be introduced to her friends can be dangerous i think.you could loose time a and the girl can be convinced by another girl that is not good to kiss you.
so i'm in doubt i don't know if is worth try to know their friends.....for sure can work but can be also pointless....what do you guys think?

Oh, sorry for the misunderstanding. Well let's see if I can still help out a little...

Well it's not like you can grab her other arm and pull her back towards you, so I would play off of what is given: she is leaving you for the time being. If you JUST met her, like you said, on the dancefloor with minimal verbal interaction, you have barely invested anything into her (value, precious time, etc.) if anything at all and like wise in her case. There really isn't any investment attaching her to you which may explain why she usually will comply with her friend and leave.

I would let her walk away and as long as she doesn't leave the venue, you can approach her later. You already opened her in a sense so I would assume she will notice you about the club for the night. I would let her see you talking to other girls or out having a good time just gathering social proof... don't do this for her, do it for you because you want to have a great time with or without her. Wait until she is off the dance floor so that when you approach her later in the night (let time pass so you don't seem like a clingy annoyance) you have time to allow her to invest in you. You can even tease her about the fact that she left you once the conversation has been going. Either make light of it OR don't bring it up at all to show it doesn't bother you. If you do bring it up, say something playful like "Oh, you're lucky you left when you did because I was about to serve you in a dance off." with a smirk.
The bolded parts are things that work against you. Yes, her friends can try to make you leave, and yes, they have the power to convince her not to kiss you... but if you took the time, no matter the duration, to just extend yourself to her friends, it would reduce the chances of them doing something to spite you. Give them just a minute of your time to be cool with them, and if they see youare a COOL guy and you just like to have FUN, well hell, they may approve of you and encourage her to hang out with you. Also, you never know who you will meet through them.

For example, last year in college it was first semester and I was at a club. I approached a table with three girls and two guys. When one of the guys got up from sitting next to my target, I went and took his place. I asked my target for a light and teased her on the kind of cigarette she was smoking (Newports are like a step below crack ). It sounds dumb, but it was a reason to keep talking. At first I got a negative vibe from the other girl and I could tell she didn't want me there. I ignored that feeling and stayed anyways. I started bullshitting around with the remaining guys and they quickly accepted me. I made a point of having my target introduce me to the other girl since she was being "too quiet for her own good". When the guy who originally left came back, the quiet girl told him to leave and then went on to tell me how he was creepy and just sat down and started hitting on my target. He made no effort to make the others around him comfortable and in return they didn't want him there.

Even though it didn't go anywhere after that, both girls are now really good friends of mine and we hang out regularly.

Moral of the story is: I still think befriending those around you and those associated with her is a good idea. It reduces the chances of being looked at negatively. People, in most cases, seek the approval of their friends. If your friends were hyping up a girl and you met her, your perspective of her would be greater than if your friends were talking negatively about her. The goal is to get her friends to speak positively of you so her perspective shoots up. It's like creating social proof out of her friends.

hi vegas good answer.....what you said for sure make sense
can i ask you how old are you,i'm just curious (you don't have to answer)
i don't know where you come from but i come from italy and here the situation is very hard.....if you think that you can go in a club full of italian girls and kiss one of them every night you are dreaming.....at least for normal people.
so for have fun we must go in touristic clubs full of american girls or turist in general.
there is much better,you take the advantage of the more open mind of americans anc you also use the situation that they are in holidays so more open to kiss or have a new experience.
sometimes in this situations girls are really drunk and quite easy but you have to act fast take the girl and don't let her go otherwise there will be other bunch of guys ready to approach her and probably they will kiss her.
you said if a girl leave you you can show her you are talking with another girl and then approach her later.....this make sense but not for my experience or at least not for the situation that i explained you before.
in the clubs that i go there is no time if the girl leave you there will be high probability that someonelse will take her
i remember one day a friend of mine kissed and danced with a girl but after a while he had to go to the toilet.
5 minutes later he came back from the toilet and the girl was kissing and touching another guy so......

I'm shooting you a PM.
Unless you have time or a lot of value invested in the girl, I would just go to the next girl. If the trend is at these clubs is that girls just jump around guy to guy hooking up, then be that guy they jump to... well I guess that depends on your motives. If you are out looking for a good time and just to hook up, then yes, be that guy. This can be done by using social proof or making yourself stand out. If you are looking for a "nice" girl to possibly date, then I'd say don't go to those clubs for that haha.
