As far as I'm concerned, it can mean pretty much anything. They could like you, or may have been thinking about something and didn't realize they were looking at you as they did it, or you caught them staring and they didn't know what else to do.
She's happy
He likes your smile / he hates seeing you sad
Smile, always smile.
It's actually a smile like this: :). But some email servers turn it into a J when it is sent for some reason.
Well it could mean that they don't like to smile because they feel that they don't have a pretty smile or they are an unhappy person.
No. If someone is smitten, they are in love.
There are several reasons why someone looks away really fast when you smile at them. It could mean that they like you, it could also mean that they are really shy.
someone who is crazy and to smile
A smile is the biggest stress buster of all time. It can bring back cheer in the life of someone.
It's different because when someone grimace they look at you as if you disgust them truly. But, if you smile at someone they smile at you with joy, happiness, and as if you mean the world to them.
he is liking you
It means to be as nice as your smile is. Like if someone would say, 'that's one mean jacket', they are complimenting it, right? So, replace nice for mean. : )
it means that he sometimes like you
