I had a friend with a 4 year old daughter. I lit a cigarette, and the little girl wanted to see my lighter. I took the opportunity to teach her fire safety. I told her if she got burned, it would make her ugly forever. Exact words were "You're a very pretty little girl, and it would make you ugly forever." (There was a guy I went to school with who had had his face burned off, and I had seen it first hand.) The little girl took it to mean that just touching the lighter would make her ugly forever. After that, she would not go anywhere near my lighter, she wouldn't touch it, she was afraid to even look at it. I instilled a superstition into that girl by telling her that getting burned would make her ugly forever. Her mom wasn't too happy about that, but I figure better to scare the daughter a little, and have her not play with lighters.
I was just thinking about it, and I thought perhaps Multiverser players might be interested in that. The way superstitions are born. Someone tells you something, and you believe it, and pass it on. Now it is superstition, based in fact, or in fiction. Anyone else have any other thoughts on that?
