It means his friend just said something along the lines of "Bro, that chick is checking you out."
It could be, I've had some of both, yes and no. It could mean that your 'someone that hates you' is saying something bad about you, but your friend could be just listening to that person, or, if your friend agrees that whatever bad the other person is talking about you is right, then your 'friend' is probably not really your friend. You should try talking to your friend about it.
It could probably mean that you're staring at her, so she's staring back..
nothing....
ignore and mind your business
i think someone has a crush
no if he does then looks away if your staring back then he does
They like you but they're shy to express their feelings. and maybe they are just staring at something behind you.
It most likely means he likes you but doesn't want you to know so he looks away and acts like he was never staring in the first place.
hey may like you or he wants to be friends but if your friends he may like you try to talk to him or he may just be staring into space just ask him if your friends
Because he likes you and is jelious of your boyfriend
...it means that the guy you like, likes you!
Just because someone looks at you, it doesn't mean that they like you. Yesterday, I was staring at a woman in the grocery store because I couldn't believe she had left the house in pajamas and hair rollers.
