>>Okay, I think I got a bead on this: peeing in the shower is adult, not peeing is the shower, not adult. Gotcha.<<
Uh, no. That is not what I am saying.
Avoiding a thing just because it "seems wrong" with no, I repeat, NO evidence to support the "feeling" is what children do. Mature adults are more free than children because they have the intellectual maturity to make decisions based on information at their disposal
It is not the activity that is mature or juvenile, it is the REASON for participating or abstaining that is.
Ever hear the story of the woman who cut the ends off the ham before she put it in the oven...?
No, let me guess, she pees in the shower too, and, on the ham.
I can think of no REASON not to plan ahead, and pee before I get in the shower.
