I participated in a lively discussion about showering today on a friend's Facebook page.
What struck me the most about it was not the whole back-and-forth of how often it's appropriate to shower, but how many of the posters considered a daily (or even twice daily) shower as a necessity. And how very arrogant and wasteful that is.
There are places, even in our own nation, where water is a precious commodity, but some of us treat it as if it were unlimited and all ours. Even though our pocket of the world is not suffering from drought, doesn't mean that we should treat water so cavalierly. We are all interconnected and water is valuable whether you have a little or a lot.
