No, we wouldn't want that. But, since I'm not a superhero, I'll just say laundry day for me is Monday. Unless I get behind and then it's Tuesday. Or, if I have an upcoming vacation/trip, I might get it done on the day before, in which case the day varies (and then there's the whole season transition where you're pulling stuff out for summer/winter, realize the dusty clothes need some TLC and a good washing before being worn out... you get the idea
)
