If my crush always smiles at me, does it mean he likes me more than a friend?

It's hard to say if he's just smiling. Try to notice anything else. For example- does he tease you? stare into your eyes? (or look in your eyes look away and then look back?) does he always seem to try to stand close? If the answer to these questions is yes- then congrads! he's into you!

Please try to answer my question!

maybe he was hungry, or he might like you, or both...who knows? guys are strange.

I mean you need some more hints...but that's def a good sign :)
