It is true that my brother did the washing up for our mum, but I would argue that a lot of the work was due to avoidable inefficiency (he was a firefighter arsonist; half the kitchen would be covered in oil when he used a pan, and mum would just see the mess, not who made it, and then he'd be get the credit for cleaning it), and that I contributed roughly the amount that I consumed, because back then I would offset the occasional shared meal by occasionally doing the washing up for everyone.
