I can be down low
Or float up high.
My goal is just
To reach the sky.
If I am too close
I won’t be noticeable to your eye.
And when you look again,
I’ll have flown right by.
Some think they can touch me,
So they’ll try,
Soon to find it’s impossible,
With a big sigh.
Some children hate me
So they start to cry,
While others don’t mind me,
And think of me as their ally.
Sometimes I make things wet,
And other times I keep them dry.
Some think I look like an animal,
Or maybe even a slice of pie.
What about a toy,
Or could it be a guy?
No matter what you do
I will never die.
Now take your best guess,
What am I?

Answer: A Cloud
