smile at him back.. that's a really lame question.
he smiles at you, copies you
Usally if a boy smiles and stares at you and likes to hang out with you
He like/has a crush on you
Probaly love!
That you're funny looking.
when he looks at you continuously and smiles at you
just act your self and smile at the boy boys love smiles :) x
that boy likes you or wants to be your friend
It probably means he likes you.
Not necessarily, but if he asks you out or something, then definitely.
he looks at you a lot and he smiles at you.
Likely that he's a nice person.
