My anger is made from-

The burning sun

the scolding magma of a volcano

 The anger of everyone in the world.

I found it-

Trapped in a draw

Hiding in a pot

Not wanting to be seen.

This anger can-

pry open bars of steel

Break the biggest mountain in the world

Destroys anything in its path.

If I lost this anger-

Happiness would spread around the world 

Making people more joyful.
