I am a person who feels guilty for crimes I have not committed, or have not committed in years. The police search the train station for a serial rapist and I cover my face with a newspaper, wondering if maybe I did it in my sleep. The last thing I stole was an eight-track tape, but to this day I'm unable to enter a store without feeling like a shoplifter. It's all the anxiety with none of the free stuff.
The great fun of doing new plays is that people have no idea what's going to happen next. That goes quite soon, as people start talking about it, and the only way you can keep hold of that is genuinely to keep changing it.
