How can I get to know this girl?
The other day I found out that a girl I knew was on my math class. I only saw her a couple of times a couple of months ago, but she recognized me. She then added me to facebook. I tried to talk to her and she actually seemed pretty interested in talking with me. We haven't got the opportunity to sit together in class due to class overcrowding, but she told me today that we should try to sit together. We haven't really talked that much, but every time class is over I wait for her to get out and say hi and she seems pretty nice. What can I do to get closer to her?
