Tragedy?

Chuck Schumer was visiting a Washington D.C. Primary school and the class was in the middle of a discussion related to words and their meanings. 
The teacher asked Mr. Schumer  if he would like to lead the discussion on the word 'Tragedy'.
So Mr Schumer asked the class for an example of a 'Tragedy'.
A little boy stood up and offered, 'If my best friend, who lives on a farm, is playing in the field and a tractor runs over him and kills him, that would be a tragedy.'
'Incorrect,' said Schumer. 'That would be an accident.'
A little girl raised her hand: 'If a school bus carrying fifty children drove over a cliff, killing everybody inside, that would be a tragedy.'
‘I'm afraid not', explained Schumer, 'that's what we would refer to as a great loss'.
The room went silent. No other children volunteered. Schumer searched the room. 'Isn't there someone here who can give me an example of a tragedy?'
Finally, at the back of the room, little Johnny raised his hand and said: 'If a plane carrying you and Mrs Pelosi and The Obamas and Mrs. Clinton was struck by a 'friendly fire' missile & blown to smithereens, that would be a tragedy.
''Fantastic 'exclaimed Schumer, 'and can you tell me why that would be a tragedy?'’

'Well', said Johnny, 'it has to be a tragedy, because it certainly wouldn't be a great loss, and it probably wouldn't be a fucking accident either!'
