I get quite a few girls randomly adding me on myspace and facebook, and I always do what they do to guys by asking ''Hey, do I know you?''. Now they always reply back with ''No it was just a random add, hope you don't mind?''
I just want some ideas on good ways to reply back to this. What do you guys think? Should I neg her? Should I just agree with it and change the subject? Or should I get her to qualify herself somehow?

Was curious about this myself... a good way to make conversation with them. Not sure what to say afterwords, had this happen today though, I tried this but it seemed to fail...

Scott
Hey do I know you?

Lindsey
i dont hitnk so... sorry i had the rong person my badd

Scott
nah its all good, no big deal.

Lindsey
hah okk

Scott
so who are you anyways?

Lindsey
lindsey [Last Name Omitted]...

Scott
oh come on you can do better than that

Lindsey
ha what do u mean?

Scott
i mean if we're gonna be friends on facebook thats serious business, so you should tell me about yourself

Lindsey
hah well what do you wanna know?

Scott
Throw some basics at me. Where are you from? <===[Feel like this is where shit goes south, shouldnt have asked such a lame question]

Lindsey
yeahh.. im actually about to get in the shower ill talk to u later

Scott
its been a pleasure meeting you

Lindsey
u too

Any feedback on this would be much appreciated as well.

if they are local, thats a plus. Ive added a girl on myspace, she messaged me "do i know you?" i respond "im just adding some locals hope you dont mind" and eventually we come to terms that i live next to her university and that we should meet up for lunch, eventually set a movie date. this was back in 06 for me.

thats one way.

I saw this somewhere else on the forum like a month ago...It went something aloong the lines of "Didn't your parents tell you never to talk to strangers... "
