i just had lunch so I'm back for some more advice
for gods sake please don't post too many wallposts on facebook because their friends will get defensive, and you have about 30 seconds to talk to a girl before she knows you're just hanging around, after that they know you're there and she'll feel uncomfortable so work fast and start off easy, get her to talk about herself which will make the convo lengthy and will stretch out for awhile, don't blurt out 'WILL YOU GO OUT WITH ME!?' just invite her to something like a movie or a lunch with other friends, make her feel comfortable before doing anything hasty, she needs to know you're not after her as just an object but as someone you want to be with
I'm done for today XD i'm going to the arcade lol
