My parents never raised their voices. Ever. And I never had a problem handling conflict. (And as for those a-hole coaches, I'm sick of seeing fat, loser coaches yell at kids to the point of abuse, something they seem to do at all levels, from college down to sub-PeeWee leagues. What I find stunning is watching a group of parents sit passively on the sidelines while one of these pompous, unathletic a-holes abuses their kids in public. Not much you can do in these situations, since calling them out will mean you will have kids, coaches, and parents all ganging up against you. But I do report it to the AD or the rec league, and occasionally, mirabile dictu, that will get results.)
