In the Gardens the last of the decorations are being taken down. An upside-down Santa’s face leans against a chipped two-dimensional reindeer. A child screams from its fur-filled buggy. Bright yellow men are carrying, just, a slab of decking as wide as it is long. For some reason there are seven men on one side and four on the other. Nobody watching is surprised when their path, from a straight line towards the gate, becomes a graceful, then lurching, arc into an iron-railed corner.
