The bishop, however, is unperturbed. He tells my mother that he likes wanking very much and they embrace jovially by the chapel door.
I am relieved when I discover that he was reared in war-time Bristol. 'Wank', my mother has often explained to me, was a blameless word for a walk in the West Country dialect of her childhood. She only learned that this was a localised definition on her first day as a London career girl, when she told her new colleagues of the lengthy one that she'd enjoyed before work that morning.
My mother and the bishop are thrilled to share a lost verbal heritage and wank side by side all the way across the churchyard. And I follow at a safe distance and reflect on the unpredictable social adhesives that can bind strangers.
