I was in rehearsals, waiting behind a door to come out while a couple onstage were having a row. They started throwing furniture and a chair lodged in front of the door.
My cue came and I could only get halfway in. I stopped and said, 'I can't get in. The chair's in the way.'
And the producer said, 'Use the difficulty.'
I said, 'What do you mean?'
And he said, 'Well, if it's a drama [you're acting in], pick up the chair and smash it. If it's a comedy, fall over it.'
This idea stuck in my mind, and I taught it to my children -- that any situation in life that's negative, there is something positive you can do with it.
