When he smiles at you, he says hi and you really dont talk to him, he stares at you. If he knows you he tickles you alot, he brushes his hand against yours, sometimes a boy can be mean and pick on you alot.
If a guy likes you then when he talks to you he have this smile on his face it looks different to a normal smile and when he talks to you he will look you in the eye and try to look to see your expression on your face. He will laugh at things to do with you that are not funny. He will find was to touch you like on the sholders or even just a small nudge.

Guys find it hard to get the hint that a girl likes them because they may not know how to read body language.
body language
If you look at her body language it will tell you if you dont know how just ask her out.
She smiles at you when she looks at you, and she also seems to want to see you again beyond what she HAS to do.
It is generally recommended to approach the topic indirectly and gauge her interest through conversation and body language before directly asking if she likes you.
Body language, etc.
Coming from a girl, she may be shy around you and keep smiling when she sees you. Or if shes a chatty girl then she make obvious herself. read her body language.
He either likes you more than friends or he is a pervert that touches every girl by body language.
Most likely. Body language speaks way louder than words; even if the girl herself won't admit she likes him, chances are she does.
maybe ima girl and if i do that she might think you like her
Just ask him. He will let you know with his mouth or his body language.
Check her body language - if she licks her lips, crosses her legs towards you or touches her collar bone while speaking to you it's a good sign!
