According to my mom, my maternal grandmother would say that if you can't sleep, you should scrub the kitchen floor. If you feel antsy and anxious and can't do anything about it, at least do something useful and clean the house. As I was scrubbing the floor today with Cake playing loudly in the background, I thought of her, and my mother, and the days I would spend as a kid with my mom and brother cleaning the house. We would always scrub the floor by hand; we only got a mop when we hired cleaning ladies. As a result, I am perhaps more comfortable getting down on my hands and knees and scrubbing than I am weilding a soapy mop.
Which isn't to say that I don't want a mop in the apartment.
