you can't really unless they say they do
He stares at you a lot and talks about you too.Trust me I'm a popular boy that hangs out with popular boys and this is what we basically do.Also if that boy has a best friend that is a girl and you are good friends with her ask her if that boy likes you and snap! You two are dating in no time!
you would know if a hot boy likes u if he makes you laugh!Dont forget let the boy be good!
This normally means he also likes you but cant find enough courage to say so
he would act strange and wierd
Cheek, neck, possibly lips
You would admit that you are screwed.
He probably does like you, either that or he thinks of you as a close friend, but i would say he likes you.
it means he likes u i would know i am a boy
That he wants to be friends or just wants to talk. A smile is a invitation (: -kriss
They would often make eye contact with you and they would flirt with you a lot. They would also try hard to get to know you better.
That he is shallow.
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
