Dear Mr.Smile...

Why are you always smiling?
You should put some other kind of facial expression.

Yes
I want to
But I just couldn't throw away this smiling face
You know how funny my face when I put up my serious mask

But, at least try to toned it down
If you sad, try to at least show some sadness on your face

Why should I?
I know I'm sad, but I want other people to be happy.
If my smile can brighten up other people life
I'm gladly to smile even more
It would be enough to conceal my own sadness
In someway, I can get my satisfaction
Just by smiling

Shuun
