Hmmm... well, I have goofed and once I really ticked DD's teacher off by correcting bad grammar in the textbook... It wasn't the end of the world. I talked to her in person and made sure she understood that my complaint was not with her personally, but with the curriculum materials selected by the district (which she was required to use.)
Anyway, we are on friendly terms now...so don't lose hope
If possible, try to have a face-to-face meeting instead of email. Then the friendly tone of your request and your desire to have a good relationship with the teacher will come through! I think that was my real mistake in that incident...I had sent a note to school with DD which was misinterpreted by the teacher.
