Choose one mug to be your Designated Mug I Use For Coffee Every Morning. I have a tendency to not wash dishes unless I need them to use right now, so mugs are one of those things that I will shove to the side while washing the dishes I have fewer of, like my one cutting board (I used to have three, whatever happened to the other two?) I only drink coffee once a day, but somehow, whenever I finally get around to washing all of the dishes, there are at least a dozen dirty mugs sitting there. (I suspect that dirty mugs may breed on counters. There certainly always seem to be too many of them to fit in the cupboard once I finally get them clean.)
So, the last time I got all the mugs clean, I chose one to be my DMIUFCEM. As soon as I am done my morning coffee, I wash the DMIUFCEM, so it will be clean and ready for the next day. Haha, just kidding. The next morning, while my coffee is brewing, I search the house for where I left the DMIUFCEM, and wash it out when I find it. It just had coffee in it less than a day ago, and it's about to have coffee in it again, so a quick rinse will usually suffice.
