MIL and her friends asked to stay in our house while we were on holiday. No issue with that at all, we live by the sea and people often stay here when we're away. We've been home a week and gradually realised that two mugs, about three glasses, burn on the rug from the fire and a mug ring on bedside table.
Now to be very clear, I really don't care about any of that. I'm dyspraxic and the clumsiest person I know, so done of my everyday crockery or glassware is particularly expensive and I'm the person most likely to break something. I also expect stuff like this to happen when you let people stay at your house, but I'm a bit miffed that she didn't mention it. Why would you not just say 'oh by the way we had a couple of breakages' to which I would have said no problem, thanks for telling me?
It's pissed me off (not the breakages) and of course I won't say anything, but I think I'm more annoyed because she used to practically wrap the DCs in cling film and they were scared to sit and eat at her house. 😂
So YANBU - yes you should mention to someone if you break something in their home.
YABU - Nope, keep your gob shut and say nowt.
