When we're young, we generally don't know a ton about our parents and grandparents.
We tend to seem them as larger than life, and only seldom as real, flawed human beings, with their own secret lives.
And sometimes these discoveries aren't actually made until our loved ones have passed on and we're left to piece together the little clues and mysteries they left behind.
In that, what she found was just strange enough and just funny enough that she knew it was definitely worth sharing with the world. So that's exactly what she did.
Alex, a mother from Cardiff, Wales, discovered just how serious her grandfather could get when her mother found one of his notes eight years after his death, listing off all the people he had NOT received a Christmas card from.
It didn't take long to rack up more than 10,000 likes and 500 retweets, but the real action happened in the comments section.
"Oh God, I do this," this person commented. "Is there no hope for me?"
Nope, sorry.
"After mine died we found an old cigarette packet with a car number plate written on it," wrote one person. "Turns out it was a car which abruptly pulled out in front of him. He had written 'BASTARDS' beside the number."
"It may not be as strange as it looks," they wrote. "My mum makes a note of Christmas cards not received — not to blacklist people, but because unfortunately at her age it's a possibility they've died or moved into a care home or something."
"It's not strange. It was very him," she replied. "I'm sure he became aware of those that had passed, but my brother and my cousins are on there so we have a fair idea of his mind set and love him for it."
"My dad has everyone on a spreadsheet who they send to and if they don’t send it gets entered in...people also have A, B and C category cards," wrote one person.
They not all be bad but I feel like if someone's going through the trouble of making a physical list of names, there must be some strong feelings behind it.
My advice? Try to be careful about whose you end up on!
