No, I wasn't complaining.

My daughter related the story to all of us this evening over dinner.
My daughter is generally very accurate, and went on to describe the rest of the class, from the point she stopped reading her book and started paying attention. There were a handful of protests from the students about defining heroism in this way, and then a student suggested that terrorists could be heroes, so the class got into a lively debate on that topic instead.
My daughter told us that she spoke up in class and told the teacher that sometimes the heroic thing to do isn't the right thing to do. I told my daughter that she was completely missing the point - staying in an abusive relationship isn't heroic, it's just dumb. And it's bad for the kids, too.
My best friend was very offended by the teacher's statement and my husband was on her side. They think this teacher needs to know how wrong she was. But my husband hardly ever writes any letters - he just rewrites mine. And I didn't really think it was that big a deal, in the grand scheme of things. I mean, there's battles I'll fight - but I'm not sure this is one of them.
So I said I'd toss it out here and see what a bunch of complete strangers think.
Nice to know a bunch of you are in the "let it go" camp, too.
