The fog was so thick I could only see a few metres ahead. Luckily there was another car travelling slowly in front of me, so I followed it carefully, keeping my eyes trained on its tail-lights. We continued like this for what seemed like hours, when the car in front suddenly came to a complete stop. In the thick fog I discerned the driver climbing out of the car, so I turned off my engine and did the same. “Why did you stop?” I asked. The driver turned to me and replied. “I’m in my garage.”
