A senator is visiting a primary school. In one class, he asks the students if anyone can give him an example of a "tragedy." One little boy stands up and offers that, "If my best friend who lives next door is playing in the street when a car came by and killed him, that would be a tragedy."
"No," the Senator says, "That would be an ACCIDENT."
A girl raises her hand. "If a school bus carrying fifty children drove off a cliff, killing everyone inside ... that would be a tragedy."
"I'm afraid not," explains the Senator. "That is what we would call a GREAT LOSS."
The room is silent; none of the other children dare volunteer.
"What?" asks the Senator, "Isn't there anyone here who can give me an example of a tragedy?"
Finally Little Johnny in the back raises his hand. In a timid voice, he says: "If an airplane carrying a Senator was blown up by a bomb, *that* would be a tragedy."
"Marvelous!" the Senator beams. "And can you tell me WHY that would be a tragedy?"
"Well," says Johnny, "because it wouldn't be an accident, and it certainly would be no great loss!"
