We arrived at the pub. I never went to a liberal, co-educational boarding school, but sat in that Hampstead beer garden, I was starting to build a picture. The girls all looked like Joss Stone stunt doubles, and every single guy looked like a brief favourite of Elizabeth I: tousle-haired, charming, but with a quiet air of anxiety about them. I was twice mistaken for a member of pub staff by these people, who would come up and casually inform me that the outside heaters weren’t working or that their food had yet to arrive. I don’t blame them. My aesthetic is, I realise, increasingly that of a weary bar shift manager.
