My ex husband. And his brother.
We went on a canal boat holiday as an extended family, my MIL, my Ex, our son and I plus my BIL, SIL and their two daughters. We three ladies walking back from the shops with lunch were crossing a bridge in time to see my BIL crash the boat into the side of the canal (broke some glasses, toppled the little TV etc). On boarding the boat he glowered at his wife and said "it's your fault for distracting me" .... Same holiday, one of the girls was chatting to the other and didn't see the low branches of a tree that would brush over her head - BIL put his hand on her head quite forcefully and pushed it down - hitting her head on the boat door quite hard. Her fault for not looking. Dreadful man!
My ex and son came home - ex in a dreadful temper, son (probably 15) teary eyed. It was very foggy and waiting in traffic a car had run into the back of my ex's car. While my ex got out to examine the damage the other car reversed and drove off past them. I said to my son - did Dad blame you? Yes, apparently my son should have got the number plate and my ex had taken his anger out on him. I pretty much ignored it when he blamed me for "stuff", but not my son!
