In 15 Minutes I...
1) Took care of the dishes. This meant unloading and reloading the dishwasher. I leave anything that needs to be washed by hand until the very end and do that only if I have time. This is usually minimal, pots and pans and items that are too large or fragile for the dishwasher. I didn't get to a cutting board and an empty storage tub that needed to be washed out.
2) Cleaned off all the flat surfaces: tabletop, counters, and top of the stove. I didn't get the vaporizer put away because it has to go downstairs and I ran out of time.
3) Swept the floor.
