It means they want sex or they are just a homosexual friend.
he cares about you
It might mean that knows you like HIM but he doesn't like YOU but he feels bad so he tries to make you feel better w/ a different guy
it means that they like you and they have some sort of interest towards you
Magical things will happen if you confront him
Most likely he's telling you he likes you.
he is a goofy guy or most likely he likes you!
If he smiles at you, if he tries to get your attention by doing annoying things like kicks your chair until you look at him, or knocks your papers down when your not looking. :) Hope i can help!!!!
He has an interest in you and basically may have a crush or admires you ;)
He's intressed
It's bad to ignore a guy that you like, even when he tries to talk to you. If you refuse to talk to him, he will stop trying to talk to you.
If he tries to change the subject when you talk about dat guy you like, or gets mad or If he compares himself to the guy you like and acts weird when the guy you like is around you.
Just be yourself
