A childhood belief about weeing and pooing

I had a friend a few years back (she has since moved away) who told me she wanted to become a vegetrian. She told me that eating meat is what causes you to poop, so that vegetarians don't poop. She said she was looking forward to someday becoming a vegetarian so she wouldn't poop. I decided I wanted to do the same. I tried to quit eating meat but my mother got concerned and persisted in asking me why I was not eating my meat unless she pushed me to. Finally I told her I was trying to become a vegetarian so I would quit pooping. She laughed real loud like it was hilarious and called me a foolish little girl. She told me that there was nothing to what my friend said. Since then, I guess I'm sort of getting used to pooping as an okay thing to do.
