When it's time for bed my husband says goodnight and goes to bed.
When it's time for me to go to bed I say goodnight, then generally let the dog out, empty the dishwasher, go around and collect any dirty cups, load the dishwasher up again with what's been used since dinner, wipe the sides down in the kitchen, perhaps empty the tumble dryer and hang the clothes up, sometimes even put another load of washing on that will wash overnight, tidy around, make sure the kids school uniform is ready for the next morning, leave out their school lunch money ...
(In his defence, my husband does his fair share of jobs/housework, but when it's his bedtime it's his bedtime)!
