Cloud,
Cloud is a part of sky?
Nope.
Cloud is just a decoration of sky.
Sky without cloud is still called sky.
Cloud,
Sometime it was black,
Sometime it was white.
Sometime it was yellow,
Some time it was orange.
But the cloud will never be blue.
Because there is only sky are blue.
Cloud,
When the weather is hot,
This will only remind the people,
How importent you are.
When it is raining,
This will only remind the people,
How they dislike you.
Cloud is nothing,
Cloud is just floating in the sky.
You said that I am a cloud,
Means that,
I am nothing.
