The train to work is always full, but I don’t mind really. On Wednesday I stood next to a table and was drawn away from my book by a fat woman telling her friend about how she’d been seeing a spiritual medium. She was convinced the medium was contacting her dead mother. I could tell the friend was dubious but feigning support for her.

Initially I thought ‘I suppose it’s harmless if she takes comfort from it’, but then I decided angrily that she was being exploited and encouraged to spend her hard-earned money on a load of vague bullshit.
