Evening routines give a shared home signals for when work should loosen its claim.

When work has no walls of its own, it will keep spreading into the evening until something tells it to stop. A household needs that signal to be visible, not private, because everyone living there is affected by whether the day has ended or not. A meal at a set time, a lamp turned on, a laptop shut and put somewhere else: the point is that others can see it happen.

Agree on one small visible thing that means the working day is over. Keep it even on the busy evenings, since those are exactly the ones where the rest of the house needs to know.
