If your kids are rubbish at washing up, which miraculously results in their being exempted from this thankless task, you may be witnessing what Scott Adams identifies as "strategic incompetence" :-) I suspect my wife of the same tactic, as the thought of her greasy half-washed efforts on the draining board always gets me to volunteer to do the dishes every night.

Being rubbish at a task, at our house, results in you getting more. My youngest's crappy/lazy vacuuming job on his own room, for instance, earned him some "practice". :-)

We just don't have that much hand-washing to do. They are still rubbish at the task even when made to do it.
