So I met some girl at a club and got her number/facebook. It wasn't this past friday but the one before that. I texted her for the first time that monday, then again on like wednesday. I tried calling her last wed and thurs to set up a date that sunday, seeing that I thought I'd be busy on saturday. Anyway, she said she couldn't make it since she was busy with something at her old school. I asked maybe about this weekend, she says she has her sister's birthday. Now this weekend is a holiday on friday (in my country), and I feel like a birthday wouldn't take the entire thing to do. Anyways, I'm just wondering if I should stop worrying about her and try going for some other girl. She has never initiated a conversation with me, I don't know if that's because of her age or what have you but it kind of bugs me. What should I do GAF?
