Sounds like he stepped over the line. He should treat every student the same emotionally and teach evenly. He should give extra teaching support to those who need it and that's about it. Of course, there are some teachers who cannot contain that boundary and do this kind of thing. As someone young, you wouldn't have known this and are succeptible to this kind of guy.

I hardly remember the names or what my teachers looked like (but it's been quite a while). Those who impressed me were outstanding teachers. I wasn't interested in them for any other aspect. I had my boundaries up as a kid - I didn't date until I was in college since I was younger than the others in my class.
