My sister in law is a hoarder. My brother finally gave up and tossed stuff when she was out of town. I think it was 60 industrial size trash bags. We thought they’d get divorced because she was obviously very upset. Things smoothed over but she is not accumulating as much stuff. Probably scared he’ll toss it again. I mean he went overboard but over 30 years of marriage of this nonsense and she wouldn’t get rid of stuff pushed him over the edge.
We grew up with semi hoarding parents. We were embarrassed growing up. We have hard time with clutter. I am not a minimalist. I love my stuff but if it’s being regularly used, have value, looks good and in a good condition, otherwise it’s out the door.
