Do you ever think how germy the toilet paper holder is?
A lot of the time, the toilet paper roll gets changed while you are actually in the process of doing your dirty bidness. That is, you have a duke, use some toilet paper, run out of toilet paper, reach for new toilet paper, then put it on the toilet paper holder. With grody grody germy hands.
Then sometimes, while strolling casually through the ancestral manse, maybe you notice that the roll is empty, so while doing other chores or just brushing your teeth, you take a minute to put a new toilet paper roll on. And you touch the grody grody germy toilet paper holder that someone else touched with shitpaws.
For the love of God Almighty, people, please wash your hands after touching the toilet paper holder for ANY reason.
