My strange uncle

Today, my mom tell told me, we have a distant relatives relative will go to my grandmother's home. Therefore, I Me and my sister will also go to visit my grandmother. (Your grandmother isn't your sister's? I'm curious to know. Maybe it's better to use "our" instead of "my".)
When we get got there, I saw a boy sitting on the sofa.

"He is your uncle." my mother said.

"What!? This boy??" I couln't believe that.

"How old are you, boy?" I asked the boy.

"21." He answered me. "But I'm your uncle." He added.

"Why? How? You are only 3 years older than me!" I said.

"Yeah, but I'm your mother's brother.". He said.

In China, status of a generation in the family is very important, we must make it clear that seniority in the family, young and old, etc. , or else will be considered non-Business Planning. (It's a better saying.)

so Therefore, I have to call a three years old than me older boy "uncle"...
