Cornwall in June, a heatwave. Walks with Chantal, Olivia, Charlie, and Lee. Chantal’s show, with paintings of Olivia, Charlie, and Lee. Saltwater swims, dog-spotting, charity shops. Pastel houses dripping with succulents. Train rides with real-life characters: caravan parks, birthdays, and the immortal line—“Are you two a couple?” … “Y.” … “Well, congratulations.”
