ask her out ...is she hot???
Well . . . how does she look at you?
If it was a girl then he probably likes her
Yes or he may be homosexual
it really just depends on WHERE you are when he sits next to you
that she wants to know you more or that she likes you
He may or may not like you. It depends. Do you switch seats everyday and no matter what he sits behind you? If so, then yeah he probably likes you or hes a stalker (lets hope he just likes you) but if you sit in the same seat everyday and he always sits in the same seat as well (behind you) he may or may not like you. Maybe he just feels comfortable in that seat.
It could mean he likes the girl
depends - is she staring just because you are? If not, go for it!
It means she likes you! Talk to her!!!
Not nessacrily he might just want to talk to you.
that he likes you or he wants to talk to you or is yes there there are no more free sits
Well, probably yes. And stay away from her, polygamy only breaks hearts
if she looks at u all the time or is shy around u or likes to make fun of u.
