The hour when the city finally stops tuning itself

It's nearly 4am here and I've been sitting at the kitchen table with a glass of water, listening to the radiators click on and off. There's a version of every city that only exists at this hour — no footsteps, no traffic, just the buildings settling. It sounds a bit like the inside of a piano after you lift the lid off, honestly. I think I like this hour more than I like most people's daytime.
