Yesterday DP announced he was proud of himself, not only for doing the washing up un-prompted but also for wiping up all the water and rinsing the sink when he was done (he has form for leaving the splashed water sitting all over our wooden work surface, and the sink full. A job unfinished as far as I'm concerned)
I swiftly told him this was a normal everyday household activity that he should be doing by default anyway.
YABU: how ungrateful for not praising DP for doing a basic task on his day off. I can't believe you didn't have the trophy ready and waiting in the wings.
YANBU: you'd need an extension to the house to build a trophy room if you got a prize for every basic household task you did. So best not to set a precedent now.
(Obviously this is light-hearted, there was no argument or anything!)
