For years, me and my mum used to drive back to her house around 7pm. We would always see the same guy, wearing a long coat and swinging a briefcase, walking down the same road. He always looked really really happy. Then, one day, we stopped seeing him and I haven’t seen him since. It’s been maybe 8 years. Did he just switch jobs or hours? Did he die? Did he move house? I’ll never know, because I didn’t know him. And, unless he paid attention to the cars on his way home, he probably never saw me and he’ll never know that he left an impression on mine and my mum’s lives. He’ll never know he made so much of an impression that I’m writing this now about him, if he’s still alive.
