I imagine that some lab-grown 29-year-old from Woking with a mind honed to identify individuals who fit the profile of Real Londoner (as conceived of by 50 opinion-polled racist builders and their wives in the Midlands) picks a stubborn local who can still somehow afford to live here and passes him along to some creative studio.

We look out over the river to a block of luxury flats built on the site of some old docks. It would be nice to live right there. Yes. The conversation drifts to the pleasantness of warm lighting and whether anyone needs a smart home. I interrupt her to make a joke about the French Raj as he runs up the causeway. We stand there laughing. The fireworks go off behind him.
