A joke with a complicated family relationship, and finally a joke asking someone what to call someone!

Sister: "Brother, brother, you are great, even better than dad! ！”

Brother: "Yes, my mother said so."

Sister: "I gave birth to you with my father, and I am the mother! ！”

Brother: "No, then who is the person we call her mother?"

elder sister: "she is dad's mother!" "

Brother: "Isn't she Dad's sister?"

Sister: "She is my father's sister and my father's mother, just like our relationship!" "

Brother: "So the person we call mom is also our aunt?"

Sister: "Yes, you are really smart."

Brother: "So the person we call mom is also our grandmother?"

elder sister: "yes, you are too smart."

Brother: "So the person we call mom is also my grandmother?"

Sister: "Yeah, right."

Brother: "So our father is also my grandfather?"

Sister: "Yeah, right."

Brother: "What about your sister, your grandma and grandpa?"

Sister: "My grandma and grandpa are my dad's grandma and dad's dad."

Brother: "Oh, it's so complicated."

elder sister: "it's not complicated, but the relationship will be complicated after my child is born."

Brother: "Oh? Why is it complicated? "

Sister: "Because I don't know if the baby I am pregnant is your father's or yours."

Brother: "That means your child may be my brother or sister, or it may be my son or daughter?"

elder sister: "hmm."

Brother: "What's so complicated about that?"

Sister: "The key is that when my child grows up, do you call him Dad? Or call me brother? Or uncle? "

younger brother: ". . . . . . 。”
