he likes you or he thinks your hot
You're sitting in a bib.
She probably likes you. Smile back.
This could mean that she is pleasing with seeing you, I wouldn't find this to be much of a meaning honestly, not to mention that this could also mean that she enjoys your chats or something like that.
If you mean "smiles" as a plural of "smile" then it would be "Osmehe" but if you mean it as a verb "smiles" as in "he/she smiles" it would be "smeje se".
I think pretty means you are pleasing to look at. And attractive means that you are pleasing on a sexual level. So if you are pretty but not attractive, you are good looking but not in a sexual manner.
he probably likes u n just wants u to notice him
He really likes you.
She probably overheard and is amused. Next time return the insult.
It simply means "pleasing" or " VERY pleasing".
he obviosly likes you
Either he's daydreaming or thinking of how you look naked.
If she smiles then it's a YES. She just wasnt expecting it is all.
