OK then, from last year, the Battle of the Downstairs Toilet.
We have no toliet roll holder in said bathroom, the bog roll is on wide skirting. But usually when I came to actually need it, it had moved to the top of the low level cistern, so I had to reach round behind me to get it. OH was putting it back there after he'd used it. I asked him repeatedly not to do it, if I left it there then next time he would use the one on the floor, and then replace it on the cistern WTF. eventuallly I tied one roll to the radiator pipe with string, that meant at least there was always some where I actually needed it to be.
Not too long after that, I noticed sprinkles on the toilet seat. I wiped them, but I kept finding new ones. Listening outside the door it was clear OH was not lifting the seat before peeing. I tackled him, asking him if he did lift the seat, and saying I had found sprinkles. His reply: 'Well I sometimes find your sprinkles' (WTAF) I thought for a moment, and then said 'In my family's house, we were taught that gentlemen lift the seat'
His instinctive reaction to any issue being raised, big or small, is to immediately blame the other person for a similar misdemeanour, or explain that his behaviour was their fault really.
Wry amusement. Kept me going for a bit, anyway
