Belle and I squeezed into the revolving door, then sat side-by-side on the bench, taking care with the positioning of Belle’s broken leg. Then I took out my iPhone. For the next half hour or so we went round and round filming hysterical selfie videos.

CM, who went through the door just once to exit at the other side, was furious that we forced him to wait so long for us. He couldn’t care less about our filming exploits.
