During the day I can approach any girl, but for some reason at night it doesnt work. Like tonight, there were these girls and this party wasnt going to well, really boring, so im like "geez isnt this party boring?" and they were like yeh and i said they gotta get this started and the girls were like why dont you and i was like well i gotta have one of you three to help me and then they just stared and then i walked off, but like that was at the beginning and then i stopped approaching, and that was good for me, like i just cant approach at night, but during the day i can strike up a conversation at anytime

That's odd, nightgame is often considered easier to approach than daygame (for AA) and it's the same for me. But why don't you try a canned opener then? There are lots of them for nightgame

girls have their sheilds up at night, some girls plan is to be bitches and show off to their girlfriends how many guys they can give IOIs too then blow off when they approach.
Sometimes lines and things just wont break down the wall.
In the day girls arent expecting to be approached so their not on guard for players or horny drunks or ASD.
Girls like for things to just happen and 'just clicked' between the two of you so asking for a voluteer from the group might not have made any of them feel selected or special.

What a nice position to be in, day game is worse for AA. Some tips i recommend for night time game:

*Get into state - this is so important. You got to have energy at a similar level to the venue or you will be an energy sink and not a source. I have a list of songs I play to get into state. I also make sure that I approach ASAP when I get into the venue or even before.

*Live in the presence - enjoy the music of the venue, dance, have fun, joke with your wing or strangers. This will telegraph messages to people that you are comfortable in your surrounding and a fun loving guy.

*HUMOUR HUMOUR HUMOUR. Make the girls laugh during the day or night and you will close. Make sure you couple your humour with good frame control and you will come across charismatic and funny.

*Stay positive, rejections are worse during the night your ability to be indifferent to getting blown out will govern your state and as a result your success. Remember if a girl blows you out, that its nothing personal. Get over it and move on.
