It seems we all have lopsided grandparents for the most part.
My Paternal grandfather was a Polish Cavalryman who fought with the English in World War 2, from what I heard, Excellent Person, the best of the best! Moved to America, made a family, a business and did well, died in his early sixties before I was born though.
Paternal grandmother, mixed stories, generally good though, although when my father was dying (also young, 51) he told me he felt like she abandoned him and his brother.
Maternal Grandfather… Hah the real one? Decent man, no complaints, died young.
Maternal Grandmother… Old alcoholic whore, still alive and pushing 90, smoked and drank 8/9 days of her life. Treated my mother like shit, made her work to take her money to buy alcohol, beat her mercilessly, let her live on the street, until my Paternal grandfather (My Father’s Dad) took her in and raised her, even though she and my father were dating lol. I cannot stand this nasty old woman, she looks like a creature from planet of the apes and one that aged like milk, she is just as ugly on the outside as in.
(Side note. My mothers female siblings, the ones raised by my maternal grandmother, are notorious thieves, liars and scoundrels who only show up to funerals to see who left them money. The male siblings were smart, took off really young, still good men, they only talk to my mother because she has a heart and is a good woman.)
It’s amazing how one shitty person can completely sabotage a family. But we all have them! I’ve never met a person who had both excellent grandparents, It’s always one good and one bad, though. It’s nice to hear of that, I wish I had it or could have experienced it.
