I saw this when it was posted! Some highlights from the comments:

I can’t remember if I told you guys this but my grandpa paid a guy to put up a rock retaining wall in the backyard when my grandparents moved into their house in 1966. They live at the bottom of a mountain. The wall finally collapsed this year and my grandfather with dementia was PISSED OFFFFFF and he wanted so badly to call the guy who did it and chew him out for doing a bad job. My grandma is trying to explain that the wall lasted 60 years and the guy who did the work is probably dead and it TURNS OUT HE IS STILL ALIVE. Now we’re worried grandpa is going to get through to him (small town) and we’re going to see two 85 year old men come to blows over a rock wall that has been there since the mid-60s. My grandpa is a scrapper, he’s been to jail over a bar fight, the possibility that he WOULD fight this guy is high.
