Nope, she just won't touch 'em.  When selected, I can't even click on the dirty dishes.  She cleans everything else.  I have tried "influencing" her to clean, and she does the toilets and cleans the fishtank, but doesn't touch the dishes.  Hmmm.  I checked her personality, and yes, she is abysmally lazy, but the neatness score is at 5. Not a big problem, since she doesn't live alone, but I was curious to know if anyone else has such a recalcitrant Sim.  By the way, she started her Simlife as a maid who moved into one of my lots, so perhaps that may be a contributing factor.
