Here's Sir Ken in action again at TED.
The nativity play anecdote and its implications reminded me a bit of the following q&a session we once had with some of V's nephews. One came up with what seemed to us to be the perfect response:
— Y tu, que vas a ser cuando seas grande?
— Yo? adulto.
He was indeed the youngest and clearly the only one not unduly influenced by an impression of what we the incumbent adultos wanted to hear.
