Air.
You can get it/use it/breathe it without money.
The only thing you can live without using money, really.

But sometimes.
I feel like it gets mad.
Because the wind is too strong, 
and suffocates you.

No?

Hair gets messy and tangled.
Skin gets cracky and dry.
Eyes get red and blind.
Nose gets runny and cold.

But, I guess we have to say "thankyou wind."

Because really...

it's free.
