The Stepfather.

As a kid,his stepfather used to strangle him and beat him with a cane on his neck.

So when he grew up ,he gave the stepfather his daily dosage of medicines.

After breakfast,he used to smash a toe with a hammer.The lunch dose was a slit on the tongue.And the dinner was practising greek alphabets on his skull,with a knife.

He treated them with alcohol and salt,at the end of the day.

When the first month ended,he left the stepfather in the basement with a rat family.
