No matter how angry I am, I shouldn't actually say what I'm thinking to N's teacher in a return email. Because that kind of language isn't going to help, even if it would make me feel better.
No matter how angry I am, I need to keep remembering what the goal here is. Actually, I need to figure out what the goal here is, and THEN keep remembering it. Which is why I have a call in to a special ed advocate. Whether or not I already am sigh-worthy, I now need to go way past that point. And to do that, I need to bring in the big guns. I need to know what his rights are, what I can request, what I can DEMAND.
No matter how angry I am, I need to stay calm and make good decisions. But damn. I am really, really angry.
