So I am thinking this girl might be getting interested in me. I had class with her last semester and this time we met on another class and she sat next to me. I have been staying behind on this so I have been talking with her. Once, she asked me to help her doing some thing, and we were alone in some room, but I didn't do anything, because I didn't notice her very willing. Also, everytime I am doing something, she gets close to me and often make small talk. The only reason I might not be sure about this is because I asked for her number, and made sure she got mine, but haven't gotten a call nor a text from her. I guess she is either not the type of doing that or maybe not interested at all.
