Dear Dreadful Math Teacher,
I just thought I'd write to let you know a bit about the damage you did to my kids this year. It's pretty clear that you don't understand the subject you're teaching and are substituting rigidity in form for substance in teaching. My kids have suffered under you for ten months, and it's finally almost over. My daughter has lost a lot of confidence because you force her to use your kooky and mathematically incorrect methods, and she's started thinking that she's stupid. My son feels the same way. I can't decide if you're just mean or an incompetent person who capitalizes on parental love of "tough" teachers to hide your lack of knowledge. Either way, we're almost done with you, and both of my kids will regain the confidence you stole from them. They will succeed in spite of you.
