A joke about a boy bringing a girl home, and the family relationship is very chaotic.

A boy has a single father, and the girl next door has a single mother.

The two families knew each other when the boy took the girl home to play.

Later, the boy married the girl's mother, and the girl married the boy's father. The two newly formed families soon had their own babies.

Both babies are healthy. The boy's child is called Tiantian and the girl's child is called Tiantian (this is very important! ）。

Soon, the two children began to learn to speak. First, they should learn to call their families.

I learned to call my parents every day. At this time, the boy's father came, so I learned to call my grandfather every day.

At this moment, the girl came into ........... Of course, grandpa's wife should be called grandma every day.

At this moment, Tiantian came in. Since Tiantian's father is her grandfather, Tiantian is the same generation as Tiantian's father.

Sweet has to call me nephew every day! Call boys, that is, every day's father, eldest brother, and girls' mother, eldest sister-in-law.

However, every day's mother (that is, the girl's mother) said, no, the girl is my daughter and my half-sister every day. How can I be called grandma? The boy's father is my daughter's husband, that is, my son-in-law, a son-in-law and a half, and should not be called grandpa every day, but brother-in-law!

what about sweets? Sweet has to call me uncle every day! Call the boy's father grandpa and the girl's mother grandma every day.

oh, now everyone understands.

The next day, Tiantian learned to call her mom and dad. At this time, the girl's mother came, so Tiantian learned to call her grandma.

Then the boy came into ........... Of course, Sweets should call Grandma's husband Grandpa.

However, the sweet father (that is, the boy's father) said that it was wrong. The boy is my son and sweet half-brother. How can I be called grandpa? The girl's mother is my son's wife, that is, my daughter-in-law. Sweetness should not be called grandma, but sister-in-law!

what about every day? I have to call sweets uncle every day! Call the girl, that is, the sweet mother, grandma, and the boy's father, grandpa.

oh, now everyone understands better.

Tiantian and Tiantian sat together one day and asked each other: Do you understand?
