I love this guy:
One day, I was out practicing serves at the park courts. On the next court, were two guys playing a match. One was outhitting the other and winning. However, the leading player was very rude and condescending about his opponent's lack of ability. After winning the match in a landslide, he blurted out statements like "gosh you suck" and "you loser!" So I decided to teach him a lesson. I challenged him to a match and he accepted. My winning score was 6-0, 6-0. Right after matchpoint, I made sure to dance around and cheer loudly. I called the attention of everybody around us. With everybody looking, I criticized his lack of form and talent. I mimmicked his earlier boastful tone and added some of my own when calling him "the worst tennis player ever" and "super sucky at tennis." I even made fun of his short stature and junior racket. He tried to justify his graduated racket length with the fact that he was only nine years old, but I ignored his pleas and continued to laugh and point anyway. He ran home crying. That should teach him a lesson to not be a tennis a-hole ever again. Gosh, what an a-hole!
