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 really likes you.
he probably likes u n just wants u to notice him
She probably overheard and is amused. Next time return the insult.
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.
pleasing
