A childhood belief about weeing and pooing

I am told that when I was two years old I was taken on a trip through several US states, to visit my grandparents. I had no trouble that time since I didn't yet know about there being different states in the US. But shortly after I first learned about the states of the US, my family was on an overnight trip to an adjacent state. As we were nearing the motel where we were to stay there, I had to poo real bad but I told nobody because I was afraid that maybe people didn't poop in the state we were in. I tried real hard to hold it in and thought I had succeeded. But I had to find out otherwise in the worst possible way. When we got to the motel and I was getting ready for bed and had taken off my pants but still had my panties on, my sister announced loudly to everybody, "Yvonne doo dood in her pants!" Yep, I'm afraid I had pooped and made most of the seat of my panties brown! I was petrified for fear I'd done something that one just didn't do in that stste!
