Smile ;-)

Giving a smile to someone can bring joy. It shows that life is perfect wearing a good smile, take not the smile genuinely done. Some people might smile without reason, that's smile reminds them someone who inspired them. Others will say, it brings color to their lives.

I like is some one give smile even they don't know us

It is difficult to smile if you have things to worry about. But if I am out and accidentally bump into any of my friends, I do smile and show them that I feel great! (liar, right?)

Ha ha ha..Even now i am smiling. Every one used to refer me as the guy who always smile. I normally greet peoples with a warm smile. I think smile is related to some custom as well. For example in my country if there are elderly people around, we won't smile loud as a sign of respect. Wondering...ha ha ha..

Generally speaking I do smile quite often, but it does depend on what I am doing and who I am doing it with. I have discovered that smiling when dealing with difficult people works like a charm and I have noticed that politicians do it a lot. A smile puts people at ease, enables people to drop their guard because they do not feel threatened. People are more inclined to hold a conversation with you if you seem to like them, and a smile conveys that impression. It is a little odd though that we smile and show our teeth when we are happy and yet when animals bare their teeth this is threatening. I have a dog that bares her teeth when she is happy. Everyone backs off and the poor dog is confused...

I often smile. Smile make me optimistic. Maybe smile is good for healthy.

Yes, I often smile. Like what you have said, It is beautiful.It is priceless. Beside smiling makes us attractive, we are drawn to people who smile, and smiling changes our mood, smiling can trick the body into helping you change your mood. Also smiling relieves stress, smiling helps to prevent us from looking tired, worn down, and overwhelmed. One more thing, smiling lifts the face and makes you look younger, the muscles we use to smile lift the face, making a person appear younger.
