Not anything literate like English, or anything particularly creative like art or music. I came to teach psychology, which is often seen as vaguely sciency, or more often seen as just vague. Of course psychology is about people and that is what plays are supposed to be about too. You might think studying psychology for fifteen years, as I have, would give me a great insight into human nature. In fact it has just shown me how little I really know about it.
People are complex and plays often reflect that better than any book on psychology ever can.
Perhaps then writing a play is simply my attempt at producing the perfect psychology text book. Performing on stage is often a quite terrifying experience, not just because you worry about remembering your lines, but more significantly because you never know how the audience is going to react. It is even more terrifying when it is your own play that is being scrutinised by an audience. Put the two together and perform in your own play, as I am doing with Borderlines, and I think you must seriously question your own sanity. If you are a writer in the audience and your play is bombing you can quietly slope of out the back of the theatre, still anonymous, and quietly drown your sorrows in the nearest pub.
