^^ A riddle I made up for Joe's contest!!! (Aka, Simplebeast231)

>3 Let's see if I can stump ya, Joe~

~*~

I can be high, it can be low,
And all the colors of the rainbow.
It can break, it can crack,
But also mend its self back.
You can see, but can not touch,
It can come slow or move fast.
Money can not buy it,
Nor can a light, light it.
It can be any shape, or any size,
The limits are with in the mind.
It can be as annoying as a pest,
But can also be the best.

What is it?

~*~

Sorry part of it doesn’t rhyme ^^U I got a little stuck~
For other people, I will write the answer in the comment part and bring this back up once Joe's challenge is done! >D

Love Yaz~! *waves*
