Is it normal to really like a girl after one conversation?
I was in the college library doing some studying, and sat next to me was this girl who was reading a book. I felt some kind of attraction towards her and so after a while I just casually started a conversation and it just went so well, considering we didnt know each other at all. We laughed so much and got to know each other well, this girl even lives really close to me. We told each other our names and I added her on facebook but shes got it insanely private so I cant contact her at all. No messages or comments. Stupidly, I didnt get her number because I thought it was a little forward. Its really frustrating because I cant stop thinking about her and its been a week since that day in the library.
Anyway, what I'm thinking is, is it normal to like a girl a lot after just one conversation?
P.S, give me some ideas on how to make some progress with this...thanks!
