Be a Good Citizen versus Don't Be a Schmuck
I can take a two and a half minute shower and be clean and happy. I know because I just timed it. I just need to shave in the sink instead of in the shower.
My wife, who has been known to zone into Blissography under hot, running water, says she can do it too. If we can do it, you can do it.
But we don't dare. If we cut back now, this new level of water usage will be our benchmark when they insist on mandatory water rationing a few months from now, which they are going to have to do, because voluntary rationing never works.
Then, when we have to cut back 20 or 25%, we'll really have problems. Anyone who remains at normal usage now will be able to cut back easily next time.
Be a Good Citizen says do it now, but Don't Be a Shmuck says wait until you have to. It's a dilemma.
