Indeed. From the article:

> I might want to use it again.

I can tell you for a fact my dishwasher would run a whole lot less than 1/2 the time it does now, if I lived alone. Like, 1/4 as much. And that's just considering the wife, not the kids, like my usage solo vs. us before we had kids, and that's despite some things (dirty pots and pans) taking up more than 1/2 as much space as they do with two people. And it's not because I'd be doing more thorough hand-washing—I'd be doing a lot more re-using with a quick wipe, or maybe a brief run under the water, or even nothing at all (for, say, water cups). And yes, of course they'd stay on the counter (in the sink they'd get too gross to re-use, and they'd be in the way).
