Lint

Where do you come from
Little belly button lint?
I find you all the time!
Can you please give me a hint?
Are you planted by small elves, 
Trying to make me cray?
Sending me a message
To shower everyday?
It's an unsolvable mystery
Unlike any other
It clogs my favorite body part
And certainly's a bother 
Please tell me why this happens 
I can't go on not knowing
Until then my belly button
Will look like it is snowing!
