You're a Brick, I'm a Brick, We're all Bricks

 Brick: "clay-bearing soil/concrete material, fire hardened or air dried, used in masonry construction." (Thanks wiki)

I am a brick. You are a brick. We are ALL a brick.

I have been created. You have been created. We ALL have been created to contribute to the construction of the world.

Each shaped similarly but differently.

I have trials. You have trials. We ALL have trials and it is up to us to stand or crumble.

I cause pain. You cause pain. We ALL cause pain.

I cause support. You cause support. We ALL cause support. 

I am a brick. You are a brick. We ALL are a brick. We decide what we destroy or what we build.
