A while ago I was driving home in the dark. At a traffic light I saw a car opposite mine that did not have their night lights turned on. I hooted gently to catch the attention of the driver, then gestured to him he need to have the lights on.
I felt good about myself the rest of my journey home, thinking how I would appreciate it if someone notifies me of my errors. I arrived home, parked then got out of my car. I realised I’ve just driven home without my headlights on.
