there's this guy in one of my classes that was looking my way a lot. but I don't know if he was looking at me or the girl in front of me. When I did turned to look at him he would look down at the floor or the other way.
is there anyway to know if he was looking at me or the other girl with this little info?
Not really, but the rule of thumb is wait until he does it again and see if he looks away again, a guy gets tunnel vision when he's admiring the girl, so if he is looking at the girl in front of you, he shouldn't look away when you look at him.
By the way, I don't like the saying "rule of thumb", sorry for using it.
