Writing takes its toll. You don't have to do a full nano to start making peculiar mistakes -- I struggle daily with the 750 words required for novel-in-90.
Today I intended to write 'handtag' (handle), and instead found myself having written 'handfat' (basin, sink). Easily fixed, of course. Then I started to ponder the worldbuilding possibilities.
The door had no basin... M offered some assistance, and together we arrived at a society where you have to wash your hands every time you go though a door. The handles are actually *in* the basin. There are two of them, far enough apart so that you can't turn them both with one hand. And they don't work unless there's water and soap in the basin.
Now, throw some multi-limbed aliens into this world.
