Sunday night Ethan brought over Fritz Lang’s “Metropolis” but then we popped the thing into the VCR and it became clear that the synthesizer music on the Eighties remake version wasn’t going to cut it. It also became clear, right then, that we needed to watch “Splash” instead, so the boy went out into the winter for a trade-in. Over party leftovers, and sweet, kicky mojitos drunk out of jam jars, it is nice when you both laugh at the same parts.
