When I was but a wee lad, my mother was dating some guy that was liable to seizures. I did not know this. In fact, I did not know what a seizure was. One day we're all together at the library when all of the sudden my mom's boyfriend drops to the floor and starts flopping around like a fish.
I thought it was hilarious. I was a little kid and he was one of those guys who tries to gain favor with his girlfriend's kid by always being a goofball around him, so I just thought he was messing around. Then he started puking out of his nose and I stopped laughing and started crying.
