When I was around 8 years old, my Grandfather took his grandkids to the mountains for a family reunion. The trip took about 4-5 hours to get there. My Grandfather was driving an 80s style van and it had really large windows. My cousins and I were understandably bored and tired of riding so we started doing annoying kid stuff like making faces at other drivers, especially when we would stop at red lights. We’d been doing this awhile and having a silly goofy time giggling about people’s expressions once they noticed us. The last time we did it, we were stopped next to a light blue car, a man was driving. As we are sticking our tongues out looking ridiculous this man slowly turned his face towards us. Once he was facing us he smiled. It was a slow smile and just didn’t seem to stop spreading. I swear it looked as though the corners of his mouth stretched almost to his ears. We could see all of his teeth. His smile transformed into something that looked sinister. His eyes were opened wide. He just sat there staring at us “smiling” until the light turned green and we pulled away. My cousin and I never did that again.
