I’d hate to put a damper on fun, but when I was a kid, the next-door neighbor’s adolescent son was fooling around with a homemade pipe bomb. That experiment cost him a hand and an eye.
I read a children’s story called “Follow My Leader” about a boy who was permanently blinded by a lit firecracker a frightened playmate tossed in his face. The rest of the story dealt with the boy’s coming to terms with his blindness and learning to use a guide dog, and eventually forgiving the kid who blinded him. It was a pretty sobering story and I still think about it, and about my neighbor.
