I've been amazed over the years at the lengths people will go to to make the schools adapt to their personal quirks... and yet they won't volunteer to help, or sit down and make sure homework is done.
I come from a family full of school teachers, and would-be school teachers, and most of my college friends were education majors. The overwhelming anecdotal evidence is disgusting. Ask for help cleaning up after class parties, ask for volunteers to help grading papers, or try to get the parents of the one third grader who still craps his pants every day (true story) to seek medical attention... no response. Have a parent send in "Halloween Cupcakes", though, and there are letters to the school board and angry phone calls from "concerned" parents.
(Full disclosure: My wife is the volunteer/helper in our home. I stay away from the schools because I can't stand other people's children. Trust me, it's in everyone's best interest. And she brings in completely non-celebratory muffins out of respect for the Jehovah's Witness... who turned out to be allergic to wheat gluten. *sigh*)
