Yesterday night same thing happened to me but with dishes. Finding a dirty dish (in this case a skillet) when you have /just/ finished and put away all the dishes and scrubbed and dried the sink, a job well done.
(I do dishes by hand a lot lately to save electricity, though I have a dishwasher).
Ah well, I just plopped the skillet in said dishwasher and I'll wash it up tonight with the rest of today's dishes, but it bothered me for a moment!
Oh, and when I have /just/ taken off my shoes and slipped into my comfy house slippers, and then discover I have forgotten a little chore that involves going outside. (My house slippers are as fluffy as the garden is muddy, so walking outside in them is no option! XD )
