My mom is Mimi because Grandma sounded too old, she was 50 when she became a grandmother for the first time. My grandparents were Grandma / Grandpa but my parents are Mimi & Papa. It's from my sister's-in-law family.
I wonder what Alexander and I will use. X's parents are Grandma & Grandpa.
I have more to give! More words! More joke! MORE BANANAS! - Gerald
