Sports Parents!! Gaaah!

Is anyone else annoyed by aggressive sports parents? My kid loves gymnastics, and she's good at it. Great. Fine. There are other girls in her class who are good at gymnastics too. They all amaze me, those kids. Flying through the air so effortlessly. (And I'd kill myself if I tried those same stunts!)

There's always gotta be just one parent out there yelling, taking up the teacher's time, and in our class's case, hogging up the one or 2 viewing spots so that other parents can't watch. What gives? Are people living through their children? Are we so competitive that we even have to compete through our children?

Is being this competitive a bad thing?
