Doing the dishes can be annoying; you've just ate, and you'd rather sit for a bit and read, or stare at the sky with your walkman on, or just about anything else. But you also get to see the tools of the meal, what was used to put it together, and learn a tiny bit of responsibility, and discover that there are ends of things you ordinarily wouldn't think about.
At this point, I don't mind doing dishes most times, because I always get neat ideas when I do the dishes.
