Search Results: spark a conversation

In my psychology class I noticed this one girl that would always look at me and smile. I only had brief conversations with her but every time she would see me she would wave and smile.
Last week after the test I noticed that she was dressed less conservatively than usual and that sparked both concern and interest. She usually dresses very modestly but this time she dressed more revealingly. Although it made me more interested I became concerned that she would be just like those other girls that rejected me. I tried to talk to her after the test but she seemed to be in a bad mood even though she was really energetic. Yesterday I saw her in class and again she gave me this wide smile. I approached her and tried to talk to her but she would barely respond claiming she was tired. I told her to try and push the coversation by bringing up any topic she wanted to discuss but she just sat there waiting for me to say something. Even when I'm tired I can still push myself to talk to people and to do whatever I desire so I see it as a big flaw in her that she can't do the same.

The next class is on Monday. Should I give her another chance or move on and try to find someone more outgoing?
