Hey OP, let me tell you my side of the story if that helps. Back in school, maybe 8th grade, i was playing some outdoor game with my classmates during the games period (PT class). We divided us people into 2 teams. One of the girls, who cheated in the game, and i called her out for it, started arguing with me, and started shouting on me. She used to be very bossy and dominant and often tried to get things her way like that. So, me being a calm and gentle person, got heated and wanted to go out of my character to give her a taste of her own medicine and shout back at her. "Don't scream at m-mh- mh- m- mm-mm- m-" (me) And everybody, in both the teams erupted into laughter. The argument ended that time and there only. The girl who was arguing with me, could not hold a straight face and so couldn't anybody else. They all went back into the game and nobody even acknowledged me for taking a stand for my team. Even after all these years, that embarrassing and self-confidence breaking moment flashes through my memory everytime i stutter on any word that badly.
