Nathan Buckley is a gentleman's gentleman and a credit to himself, his family, his club and to the sport. The way he shared how he raises his children to cheer for their team and not boo to denegrate I think is totally admirable. I personally don't boo, its stressful enough watching your team play without turning peanut because something happens on the field you don't like.
Taking it a step further, anyone who lowers themselves to the point where they boo their own team should not even attend football matches ... stay home watch it on tv and yell at the dog ... and hopefully he bites you.
