Posh' is not really political. I didn't want to aim a brickbat at the system. Or to bash Old Etonians. It was always the class and privilege aspect of that world that I was most drawn to. There is something endlessly fascinating about imagining something you could never be involved in.

It's very lucky to be able to do a job where I get to sit about writing plays all day and going to the theatre. The downside, I suppose, is that you put it out there, and people are invited to like it or loathe it.

I'm not posh at all. I grew up in Sheffield but never managed to pick up the accent - which was careless because there'd be some cache now in being a northern playwright, but I missed out on that one.

And I admit it: there's a rather dirty thrill when 700 people laugh at a joke you've written.
