the only time i saw/heard some kids laugh at another boxer, their coach yelled at them in front of the entire gym, telling them they couldn't even last a round sparring so shut up...after the parents came to pick them up, he wlked over handed the parents his coach fee back, and said i don't want them back here they were disrespectful. now my last match, the crowd laughed at my opponent, he tucked his head and threw wild haymakers,while i backed up slipped right then left then threw a puniching overhand into his cheek bone...after several times of this and his daddy yelling at him he became shall we say over anxious and his technique really went to hell. he hasn't fought since. so laugh as they may, it all comes out in the wash...
