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.
Playwrights are naturally wary and protective - God, who's more protective than a playwright? You read a play, the playwright wants to hear from you immediately.
When I was around eight, I learned how to touch-type at school, and I received a computer as a present. I started writing plays, and for many years I thought I would be a playwright.
