give me an example of a tragedy?

Tony Abbott was visiting a Sydney primary school and the class was in
the middle of a discussion related to words and their meanings.
The teacher asked Mr Abbott if he would like to lead the discussion on
the word 'Tragedy'.
So our illustrious leader 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 playin' in the field and a tractor runs over him and kills him, that would be a tragedy.'
'Incorrect,' said Abbott. '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 Abbott, 'that's what we would refer to as a great loss'.
The room went silent. No other children volunteered. Abbott 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 Mr Hockey, Mr Pyne and Mrs Bishop was struck
by a 'friendly fire' missile & blown to smithereens, that would be a tragedy.'
'Fantastic' exclaimed Abbott, '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 accident either!
