The toilet seat issue is more because if they don't put it up they, pee on it.
The lads have their own towels now that have to be kept in their rooms. They are responsible for washing them as well. This, because on more than one occasion I've gone into my sons room and found 10+ towels on the floor.
only koking if I tried to compile a shopping list during sex we'd be living on bananas leeks and sausages..
However I had one ex where I probably could have popped out for shopping and come back without him noticing he'd been feeling up the pillows for half an hour.
....OH peeing on the loo seat, toothpaste residue in basin and no top back on the toothpaste. Daughter leaves damp towel on top of her bed. grrrrr.....
