She gets riled by me ‘not finishing the job’ when I do the washing up - eg not wiping the side down properly or ‘forgetting’ to wash something up.
I can escalate things further by suggesting it would be nice for her to do the washing up for a change. Apparently there’s always loads of washing up for her to do when she gets back from work, I’m fairly sure it’s just a couple of mugs and her own cereal bowl from breakfast though.
