“She doesn’t want to change back…does she?” I suggested, as soon as I got Felicity on her own, after persuading the twins to have a go on their swings. It was almost midday, and spring was in the air, so Caroline had been happy to let us go outside for some exercise. Felicity had been dropped off around ten, but her mother stayed for coffee with Caroline, and the girls really wanted to play with us, which was sweet but frustrating. But we prevailed in the end, and after Caroline got the three of us wrapped up in our heavy red duvet coats, and Felicity had put on her dark pink overcoat, the twins dashed off to the swings and we sat on the bench where I had told my new best friend who I really was, just forty-eight hours before. It felt like a lifetime ago already.
