Questions: Flirting

Before I start, I do not like this guy, but one of my best friends has a crush on him, and she got rejected. However, I think this guy likes me? We have 2 classes together. In one of them, he sits at the table in front of me and we face each other, and I'm not that talkative in that class. But in the other class I have with him, we sit across the room from each other. But I do talk a lot in that one. Last week in the first class I have with him, I turned my head towards him, and he was staring at me, and he looked away really quickly. Then in the other class I have with him (the one I talk a lot in) I kept catching him staring at me, maybe like 10 times in one class period? I also caught him staring at me at lunch. Then when I was walking to one of my classes with one of my friends, he was standing by the door staring at me. When I saw him, he looked away as fast as he could, like he always does. I've never talked to this guy by the way, and we're both freshman

So a fellow GAGer was reading a book about relationship and he told me that the author of the book said this:

"When a man gives a woman a lavish gift, he thinks he is scoring 5 points in her book when actually that is worth just a point to her. She will mentally record it as a point. Men will always have this proclivity to award more points to a deed/gift of a larger scale as opposed to women who would count each gesture of affection/gift as 1 point."

So what do you think about this, fellow GAGers?
