" …it was during a period he had so much time on his hands that he felt that time had stopped.

How could time have stopped?

‘Because,’ he said, ‘and you will understand this when you are older, sometimes you feel that everything around you has come to an end. You feel that you are completely alone, that time is frozen and that you are invisible. At first, you might feel exhilarated by the sense of freedom, but then you’ll be frightened that you are lost and you will never be able to go back.’

He explained that when he first felt this, he had been isolated and afraid and had prised open his watch case to verify that time was indeed passing. The rhythm of the watch might have been imagined. Sound was not enough, he needed to see and touch it. It was the first time that he had dismantled a mechanism. The turning wheels, ticking each second away, had reassured him.

It was then that he had comprehended the importance of time. "
