How does brushing in the shower save water?  All that time you're brushing, at least a good 2-3 minutes if you brush properly, the water is running when otherwise it wouldn't be.

Btw, preemptive strike...lol!

(And the cats fighting the mouse thing was good too)

P.S., really want to save water?  Do what submariners do - turn on shower, get wet, turn off shower, wash, turn on shower, rinse.

(No, I don't)
