One of the assignments I took upon myself while the rest of my family was away, on top of binge movie watching and throat slitting (aka playing Shadow of Mordor), was cleaning. I spent many an hour – days altogether – carefully cleaning the house. I won’t claim to have managed to bring it to a state where licking the floor could be considered advisable, but I think I made a difference.
It showed. My son’s first words, upon entering the house (after more than an earth day of flying!) were “Wow, the house is so clean!”
And then he dragged his feet in, bringing along all sorts of muck from the outside, and started spreading his stuff all over the place again.
Thus the mathematically infinitesimal nature of the states of cleanliness and orderliness have been proved in the real world.
