There have been two great accidents in my life. One was the trolley, and the other was Diego. Diego was by far the worst.

I remember in '37 when trolley cars were so big in New York. It was five cents for a ride... There used to be open-air buses, and you could go up a spiral staircase and sit up on top. Those were great, great days.

I remember at the age of five travelling on a trolley car with my mother past a group of women on a picket line at a textile plant, seeing them being viciously beaten by security people. So that kind of thing stayed with me.

I know I'm very lucky. A lot of it is quite normal, scooting around the supermarket with a shopping trolley and things like that. With one parent being a prince and the other being an amazing sort of... business woman.
