Anger is a sweet box

For this poem, I was assigned a metaphor an i was tasked to make a poem out of it, my metaphor was "Anger is a sweet box"

Anger is a sweet box

only to some

they keep it in a box

stashed in their soul

covered and disguised

to look like a sugar cube .

But if their cube

should bust trust me

that heads will roll.

These people wait

this is a fairly common trait

until they devour

their own sugar cube.
