A childhood belief about weeing and pooing

I grew up in Tennessee. The first out-of-state trip I remember being taken on as a child was to Virginia, where I got diarrhea. For what seemed like the longest time thereafter, I thought that meant that people in different states pooped differently, the more solid poop I was used to being the kind peoiple did in Tennessee and the diarrhea-like type being what people in Virginia did. I never questioned that until one scary day when I got diarrhea back home in Tennessee.
