Finally, something on HN that I actually understand. I get what the writer is saying but have a few reservations:

- sometimes it's easier to wash things after you've left them to soak overnight or for a few hours

- it doesn't make sense to do the washing up for one teaspoon, it's better to wait until it all accumulates and then do it all in one go (that's my excuse, anyway)

- I highly doubt that doing other people's washing up will make them do their washing up
