When I travel far, I get jet lagged very badly. One night I was lying in bed in Prague at 3 am. I was wide awake, and there was no place to go, no one to talk to. The city was utterly silent. I didn't want to read in case the light woke my husband.

Then a blackbird started to sing - a blackbird in a pitch dark treeless city. I felt that it had been sent just to comfort me.
