act only according to that maxim by which you can at the same time will that it should become a universal law.

It's generally considered bad manners to let bodily fluids leave the body in public. I assumed this was a universal. Not in Southeast Asia, apparently.

This morning on our way to church Alyssa saw a man stop by a tree, put a finger on one nostril, and blow snot onto the tree with the other nostril.

I know, right?! Gross.

I've also read about people peeing on the sidewalks in Vietnam. Businesspeople, too, in suits. I'll report on this after our October trip.

I don't know about you, but I think the no-releasing-bodily-fluids-in-public rule stands up to the categorical imperative.
