One evening a few weeks ago, I was pottering about alone when I became aware of a feeling of great relief, of joy almost, without quite knowing why. When you spend every waking moment with a seven-year-old, it often feels euphoric to be alone, but that wasn’t it. By mistake, I’d left my phone behind, but that wasn’t quite it either.
It wasn’t that I couldn’t be contacted, I realised, so much as that I couldn’t be tracked. My iPhone, with its inbuilt GPS, was at home logging only its own dismal existence. The ‘Find My Friends’ function, which, at my family’s request I keep switched on, was defunct. I was unfindable. It was joyous.
