Expressionism.

But I'm trying to express myself,
My words are all I've got!
But no one understands me, and-
I haven't got a lot!

But what I say is myself at heart,
But you just don't get me!
My words are something deep, I swear,
Why won't you let me be!

But they're not mine but I say they are!
But I don't care, so leave,
But no one cares about my life-
They grant me no reprieve!

Who am I kidding? I'm a kid,
Big words? Pictures, I need...
But give me something, let me claim,
It all starts with a seed.
