“
Try it in the last hundred years or so and you’ll find the lack of National Insurance number, ID card, or credit rating means you’re officially a non-person and after America closed its borders last year, all sorts of security alarm bells start ringing. Or, you think you’ll go back a little further before all these tiresome records were invented, but that doesn’t work either. Society is rigid. Everyone knows everyone else in their world. Everyone has their place in the scheme of things. If you don’t belong to a family, a tribe, a village, a guild, whatever, you don’t exist then, either. And you can’t just pitch up somewhere without mutual acquaintances, recommendations, or letters of introduction. Life on the fringes of society, any society in any time is tough. I should know.
