how do you feel when someone give you a smiling?

I feel ike I want to smile right back  and hug the person :  )

but when  people's smile are ake. I just shrug my shoulders at them and smile by myself   :    )

That depends on who is going to smile at me...

My daughters' innocent smile is really infectious and affects my immediate behavior. I forget all pains, difficulties and worries around me.

Ultimately, a smile - even from a stranger- is heart warming and makes me feel instantly better.
