I'm constantly cleaning up after my wife. Buttery knife on the table, then wipe the table, because of the butter and crumbs, because she doesn't use a plate. Cleaning the surfaces - sugar, crumbs, whatever she's slopped out of a pan to a plate / bowl 3 feet away from the cooker - and often slopped on the floor and down the unit doors.
Rubbish from sodding Amazon parcels, left on tables, on / under the couches etc. In fact, any sort of wrappings. And that's without clearing any cups and plates.
On the rare occasion she does put something in the sink, there will be a teabag, or loads of food, which means I have to put my hands into a cold, slimy mess and get rid of it.
She learned early that I don't like mess and that if she leaves it, I will clean it eventually. I'm really sick to death of it, but I do it to avoid her getting angry and telling me she'll do it later (ie never) and just do it.
Our ten year old daughter at least puts her plate in the sin and scrapes any food residue into the bin.
