If Britain’s parents think that 10- to 12-year-old kids are the least fun to play with, then they are doing it wrong. Those years open a tiny of bubble of paradise in which you can really play without shame. You don’t always have to conspire to lose at draughts or Ludo. Out in the park, you can nutmeg your kid, dump them on their arse on the grass, smash home a hat-trick, pull your shirt over your head and run around screaming without being considered an abject monster. You can leave them in the digital dust of a Mario Kart circuit and there’s a decent chance it will result in laughter, not tears.
