Mother-in-law #1

(This is a funny dark little poem I wrote inspired by southern Mother-in-laws)

Rat shit
Cow spit
Vomit and snot!
Kittens are nice
Mother-in-laws are not!
From Hell do they rise
To hate and dispise
The wife in your life
For who knows what!
"Your hair's not right!"
They say just for spite!
"Our kind don't like your type!"
What class do they attend?
What course do they take,
To be such mean woman
to the wives that you take?
