Anyway, hoping to reduce power consumption, I got one of those meters that tells you second by second how much electricity you’re using. They work like this: you buy the meter; you switch it on; you go insane. “What the …?! It’s reading 8.1! Something must have been left on standby. Let’s go, people! Start in the attic - sweep the rooms; work in pairs; use your mirrors.” You think you’re hard, do you? Do you? Pff. Let’s see your face the first time someone switches on a kettle. I now push a teabag into a bottle of water, then stuff it under my shirt and drink it when it hits body temperature; if we have guests, I use more bottles and go for a jog.
