No he shouldn't get mad. We all stare at people.
Yes. :-)
yes
Probably being a jerk or might like them secretly?
because he is just too nervous and wants you to talk to him first or he is just wierd...
He loves the girl. i agree 99% +1 he would definitely like this person ,no offence but it is obvious he may not say hi because he is plainly shy
he likes you, he's just scared, that's all there is to it. some guys just don't have the nerve, its not a bad quality however it stops them and they miss out on a lot of opportunities.
Nope! He might be developing a crush on you, even though he has a gf
Sorry but no, I don't think so! Guys don't really remember things like that!
Maybe. Ask him. He might be staring for some other reason.
hes probably interested in you
Because he's a guy and they seem to look at other girls a lot even thou they have one. They loose interest as fast as they get it........... Just leave him alone when he has a girlfriend then when hes free stare away.
He likes you. Make a move. He's too nervous to.
