Tonight, you'll light a whole room without thinking about it.
You won't check the clock first. You won't count anything. You won't ask anyone else in the house whether it's worth it.
Two hundred years ago, a labourer in Britain could be handing over a sixth of a day's wages just to see after sunset. Not to heat
the room. Not to eat. To see.
Imagine a winter evening in an English village. Hampshire, 1775. The light is going. There is no switch.
