You don't clean plastic lens spectacles with paper as paper will scratch the lenses, though glass lenses can be wiped with paper. Wood is harder than plastic.

Toilet paper is wood, while the seats are plastic. Wood is a 2.5-ish on the mohs scale, and plastics tend to be too. So they scratch at a 2.5 with deeper grooves at a level 3, even on a micro scale. The alternative is to use ceramics for the seat, but the fragility means one rough drop of the seat and it could shatter. Metals are generally no better.

Simple sarcasm is missed more often than you realize.

Ah that's what they use to keep it dry, just do a victory dance while sitting on it

Joke's on you, the geometry of my toilet means that sit-and-pissers splash into the bottom of the seat so I have to clean the rim way more often than I used to!

People equipped with a penis standing to pee should really have the toilet seat raised out of the way

WoW! Judging the current net negative downvotes I assume that the voters were not ready for my proposal, but I swear that I enjoy several orders of magnitude less mess and higiene in my toilet seat since I did it without any drawback… good luck!
