Sleepy Serpentine

"Are you sure you want me to stay for the entire night? I mean, I could just pop you good and be on my way." So says Julia Roberts to Richard Gere in Pretty Woman (1990). A similar invitation comes News' way from the Serpentine Gallery. For the princely sum of £35 you can spend the night with, among others, Simon Popper, Melissa Gronlund, Cesare Pietroiusti and Laure Prouvost. So the occasion is not as lascivious as we make out, but the institution's first sleepover, which promises its guests "a night of creative thinking". News feels tired already.
