Coaxed into this exchange, the two strangers relaxed despite themselves. Within minutes they were even laughing. They were from Merton, they had diabetes and depression respectively, they both worked in a hardware superstore, they’d saved up for this holiday for a year. They were none too bright and not very fascinating. The woman had an unattractive snort and the man stank terribly of musk aftershave. They were human beings, and precious in the eyes of God.
