So last night I had a twenty minute conversation with a regular customer, a man I didn't have pregged previously for anything other than drinking and bad jokes. This tewenty minute conversation was about the late, great Sarah Kane's haunted suicide and last play, the harrowing 4:48 Psychosis. This man had never been to the theatre in his life and the first thing he goes to see is something by Sarah Kane . I can't imagine what that would do to your head. It's jolted me out of a few smug preconceptions though.
