re: What do you call your parents, parents?

They're all gone now

My maternal granparents, Mamaw and Papaw

My paternal grandparents, by their first names. I don't remember how that even started, and nobody else does either. They were very formal people, and it was uncharacteristic, but I did.

As for my parents, the grandchildren call my dad by his first name. My mom didn't want to have a nickname, she requested that they call her Grandmother. Kids will come up with their own ideas, so we didn't think it would stick, but it has.
