I've been trying to talk to him over the past few weeks, but he doesn't talk to me much; yet he has no problem interacting with the other guys in the class. There are only 3 girls in the class and I don't think he's talked to them.
However, I think he's warming up to me. Last week, he cheered me on when I had the ball (said "go az!") and gave me direction on how to play. While I haven't noticed him staring at me, he seems a bit more friendly with me than he was before. Does that mean that he's interested?
