If there's nothing how can you operate upon it? Just as if there's one, then there is ONLY ONE. You cannot operate upon it.
Washing machine rainbowsingularity?
It arrives, brand-new. When it's good to go you put dirty clothes in it. When they're washed you remove the clothes. then you dry the clothes. This process is repeated. When the clothes are drying, they are (slowly) getting dirty again. So, with regards to a washing machine I would state that your clothes are ALWAYS dirty. If your clothes are in the machine, you are still wearing some, which must be dirty. Should ALL your clothes be in the machine, they needed washing so they must have been dirty. That is my conclusion...
