Hugh tongue twister. I married a widow.

I have an adult daughter and a widow. My father married my wife's daughter, so my father became my son-in-law and my daughter became my stepmother. I call my father, father and father, but my father calls me father-in-law, and my daughter calls me father, but I call her mother, and I have to call my wife and grandmother, because she is the mother of my stepmother, and later my daughter and stepmother. He calls me brother, but he must call me grandpa, because he is also my grandson. Later, my wife was my grandmother, and she also gave birth to a son. He is my stepmother's brother, so I have to call him uncle, but he is my son, so I have to call him dad. At the same time, I am my wife's husband and my grandmother's grandson, so I am my grandmother's husband and my own grandson.
