Caught

I am the most poisonous person,
don’t let me into your home.
I’ll lash at the kids,
run out your mate,
I’ll have you left all alone.

I am the most poisonous person,
keep me out of your sight.
I blacken the nerves,
sicken your balance,
stir your fancies to fright.

I am the most poisonous person,
don’t let me work at your store.
I’ll mildew the cardboard,
rob the till,
I’ll leech clear through the wood floors.

I am the most poisonous person,
don’t turn the rocks that drop at my feet.
Don’t question the wretched,
Don’t blink at the night,
Don’t ask me what secrets I keep.

I am the most poisonous person,
I am rotted, intestines to skin.
I exhale vileness
once air clear and cool.
How did the sickness come in?
