For the first year or so of our marriage, she was constantly accusing me of messing up the bathroom sink, and leaving the area thrashed.
Then, we built a house with separate, his-and-her bathroom sinks.
Lot less arguing going on now-- and my side of the room is always spotless. Very enlightening.
Gee, sounds like my wife! Of course, when we bought the house with the "his and hers" bathroom sinks, guess whose side was always a mess, with hair, etc?
