I was closest with my maternal grandmother so I guess I'd say she was my favorite. She was the only grandparent I would see on a regular basis. I missed going over to her house on the weekends for pizza and movies after she was gone.
I have fond memories of my Paternal Grandma. She could cook and play a mean hand of cards. All her Grandkids learned Poker and Bridge at her table. Cribbage was also for a matchstick a point.
My paternal Grandfather died when my dad was a teen
My Maternal Grandmother was let's say a difficult personality. She did take her broomstick out on more than just Haqlloween
