Check out The Bitter Homeschooler's Wish List.
I love #1 - Please stop asking us if it's legal. If it is — and it is — it's insulting to imply that we're criminals. And if we were criminals, would we admit it?
#6 is also great - Please stop telling us horror stories about the homeschoolers you know, know of, or think you might know who ruined their lives by homeschooling. You're probably the same little bluebird of happiness whose hobby is running up to pregnant women and inducing premature labor by telling them every ghastly birth story you've ever heard.
