When I was a kid, like 4th or 5th grade, my best friend at the time tried to show me tennis. I went with him, his mom and his older sister. On the first serve, his mom hit the ball hard and wild and she nailed me dead in the balls while I was standing on the side of the court near the net post. I fell down and started dry heaving. My friend and his sister laughed hysterically till his mom yelled at me and told me to stop over reacting and walk it off. I couldn't do anything but when she yelled both of the other kids stopped laughing and looked at her like she was a fucking monster. Later that night the mom called and apologized profusely. She claimed that she thought she just hit me in the leg. I found out later the story was told around their dinner table to their dad and the sister told her mom she hit me in the balls. My friend's dad blew a gasket at dinner over them laughing and especially over his wife yelling at me and telling me to walk it off. For years after that I was treated like an honored guest at their house. It still didn't stop me from flattening the mother's car tires a few times a year till high school. That was the last time I ever attempted to play tennis.
