I would have defended him against all odds, sacrificing my own life to protect him if necessary.
This is the way I have always felt about my family.
And this is the way Amish people teach thier families to protect and respect each other. They are a simple community with values that most people don't have, they are a tight community that respect each other and watch out for thier own. In the Amish world at the age of 13 a child is already prepared to be a "adult", handle responsibility and care for others. They work for thier livelyhood and thier family all along with schooling. Something that most others never have at that age, and unfortanately never at any age.
The average 13 year old child knows none of that, they are to busy worrying about themselves, too lazy to lift a finger to help another, too lazy to work etc. The only thing on thier mind is how soon before they can turn on the TV or play a video game.
What that girl had done was something that they learned early on in life and that is to watch out for thier own.
A simple way of living with simple common sense values, a way of life where you put others before yourself. How the world would be so much a better place if more of us were this way.
Her acts set a fine example of how selfish all the rest of us are, maybe we all can learn something from her actions

Criticize or doubt her actions all you want, but why don't you first think about what you would have done in her situation, my guess is you would have hunkered down in the fetal posistion crying like a baby pissing all over yourself instead of realizing the ultimate outcome and tried to take a stand and possibly make a difference.
Your "No Fear" attitude is nothing when your confronted with a real life situation. You see it all the time now with kids now days, they walk around all rough and tough but when a situation arises they run like the selfish cowards they are.
