Is there a difference between a normal smile and a flirty one?

Anonymous
I noticed my crush smiles a lot while we are talking. We both smile a lot. He will smile while he is saying something to me, and it doesn't have to be anything funny either: he could just be making a comment on something.

A lot of the time if I say something he will laugh a little, smile, and look away and smile some more lol.

I ran into him once and he asked what was up and I just replied normally and he had this huge grin on his face lol.

When I want to make a smile flirtatious I hold eye contact longer than I should and I smile at him.

Is there a way to tell if a guy smiling at a girl is flirty or just friendly?
