You must make smile? !
It's as if you are rubbing a soft cloth on a hard board. And even if the cloth is very durable, will eventually wear out with a lot of scratches on the cloth.
Actually there are a lot of stressin our lives , we cannot always give a natural smile.
But for the sake of a beauty treatment , a healthy mind , a job and an education, we make every possible effort more and more to give a smile in our life.
But it's unnatural.It's impossible.
We are sure to get tired.
We do naturally smile,however, by looking at a cute baby,a playful dog, and a fanny comedian without such efforts.
And the natural smile heals and encourages some people around you.And they are fully energized .
But the fact we cannot look at a cute baby and dog all day long..
We must do troublesome tasks and the dislikes in our daily lift too.Then,
How can we make a natural smile ?
