Beg a joke! Complex family relations

A few years ago, I was single for 40 years and finally got married. My new wife is a widow in a neighboring village, five or six years older than me.

She has a wonderful daughter who married my father by mistake in the second year of my marriage.

So, my stepdaughter became my stepmother, and my father naturally became my son-in-law.

Two years later, my wife gave birth to a son. He is my stepmother's half-brother. I am my son's father, but my son has become my uncle.

Three years later, my stepdaughter gave birth to a son to my father, and he became my younger brother, but this younger brother still had to call me grandpa.

I am the husband of my wife, but my wife is the mother of my stepmother, so I want to be my own grandfather.

In this family environment, my mind completely collapsed. I really can't live any longer, so I have to die.
