Go up to him and say hi. If he says hi without laughing or anything, he probably likes you. If he picks on you, he probably likes you. Ask around to see if he likes you.
just talk to her. get to know her better :)
how do you know if he likes you?well its hard too know for definite without asking..sometime's he'll joke and carry-on because he's too shy to show his true feelings ..

Changes in behavior he would show it with his body language and you can feel it too
By asking him.
if he like follows you around or stares in a amazement. just act normal.
Thats hard, but who cares.Give him a note, tell a friend to, etc. Anything that lets him know what your asking.
Go kiss them and see
Send the person a message asking something. According to his/her response youll have a clue. If such person likes you, he has to manifest anything, otherwise you are losing time. If a person likes you there are a lot of ways to know.
