There's a scene in Anne Tyler's THE ACCIDENTAL TOURIST where the protag, who's gone into safe mode after too much emotional pain, starts doing odd things to accomplish daily tasks. My favorite is that he washes his clothes as he bathes, throwing them on the shower floor and sloshing them around with his feet.
Of course there's Kramer on SEINFELD, who prepares salad in the shower as an efficiency task.
I fear that if I were alone very often or very long, I would become like them, giving up Civilization and succumbing to the lure of Easy. Prepare meals? Why, when there's a carton of ice cream in the freezer. Dust? Only if someone calls to say they're coming over. Change clothing? Not necessary more than once a week, except the really basic stuff.
I could easily find myself staying up late some nights and going to bed at 8:30 on others. Rising at 3:15 or sleeping till 7:00. Leaving the dishes in the sink several nights a week. It bothers me when I get up in the morning and they're there, but not enough to worry about it the night before.
I guess what I'm thinking here is that my husband is a civilizing influence, though he doesn't know it. Just having someone else around pulls me into a schedule, a desire to get things done.
And I thought I'd civilized him!
