I think we all knew there was more to this story. An extension cord was involved. Dumb kid didn’t think electricity and bath tub electrocutions applied to her.
I guess I’m old, but it seems to me that back in the 1950s-1960s, kids knew about this stuff by the age of 8 or 9, if not earlier. (I got my first electric shock at about 5, by sticking my hand into a lamp socket. There’s never been a second ;-)
