There's this girl in two of my classes who keeps checking me out, always playing with her hair around me, etc. It's the usual attraction stuff. Anywho, I start up a conversation with her about an assignment, but I made a mistake. I accidentally called her by her name even though we haven't met formally. I may have saved it by mentioning we went to the same high school, but I didn't tell her my name (hoping that this would make her think about me later). What's the best way to follow up on this? I was confident and didn't lose my cool, so I'm thinking there is still a chance.
