In childhood
Happiness is a marble inlaid with flowers.
I am outside
Flowers are in it.
When I grow up
Happiness is an examination paper of Zhang Xinwei.
I'm at this end
The score is over there.
We'll talk about it later.
Happiness is a warm picture.
I saw outside.
Family's inside.
Now
Happiness is a short encounter.
I'm at this end
Where are you?
