" Now the dressing-room full of RSC hierarchy. Suddenly Trevor Nunn pushes his way through and 'Trevs' me. I've heard a lot about this 'Trevving', but never had it done to me. From what I'd heard, a 'Trev' is an arm round your shoulder and a sideways squeeze. But this 'Trev' is a full frontal hug, so complete and so intimate that the dressing-room instantly clears, as if by suction. I'm left alone in the arms of this famous man wondering whether it's polite to let go. "
