Water, water everywhere

I've been thinking. Not particularly hard (as will become evident momentarily) but thinking nonetheless.

People ae always harping on about people wasting water, but I submit to you that this is, in fact, impossible.

Think about it for a minute: any 'wasted' water goes down the drain. Where does this water go? It either goes back to the sea (via the sewers) or back in to the water table where it will eventually reach a river somewhere. Whatever, the water always ends up back in the sea eventually, where it evaporates and becomes rain, which then goes back in to lakes / rivers, whatever. It's a closed system. So, next time someone accuses you of wasting water, refer them to the water cycle. And then go brush your teeth with the water running.
