On a recent trip to Tesco we parked in a family space and I stayed in the car with a sleeping child. I counted 4 cars leaving the family spaces with no sign of children and 5 cars arriving with no sign of children. It was very tempting to run up to all the people I saw and tell them “You’ve left your child in the car/the shop!” in a panicked way followed by “Oh, my mistake. You’re just lazy twats”
