This happened to us this year with DD8. Her teacher emailed saying that DD's behavior and grades gave her no cause for concern and she did not see the need for a conference. I read it as "I don't want to meet with you and will be annoyed if you insist" and caved. In retrospect, I really wish I hadn't. The especially weird thing about this is that in fact, we aren't getting the message that her behavior is all that great, though grades are very good.
