It really depends on their face expression, vocal expression, and their actions. Or they might just be naturally shy. Ofcourse, if a boy goes, "Hey, what's poppin'?" Then, you'll know they like you.
This normally means he also likes you but cant find enough courage to say so
i think that it means this boy likes you back but he does not want you to know but i am not so sure
It means that he likes you so much that he is willing to brag about you.
when a boy likes you, he'll call you names and mess around with you. another way a boy could like you is if he says he doesn't like you, he does its just so you think he wont or to impress his friends.
You can tell that a boy likes you if he looks at you a lot or he will send you a note sating that he likes you
Well, he may try to say something to you. Like maybe how much he likes you, or how he feels about you. He might ask if you like him back. You never know how much that boy likes you so you never what your reply from his actions will be. ;)
you know if a boy likes if he gets nervous when he is around you, stumbles alot when he sees you, and he is always finding an excuse to talk to you.
If she doesn't talk to him he won't know she likes him so get talking.
if he's always near you and always flirting with you and sometimes if he hits you and messes with you then he likes you
if he farts on your face
Ask him
when he does anything to talk to you
