I got rid of course titles and anything else that might identify the student, the school, or even what year this email was sent. I've left the pronouns in--it would be too distracting to read the email with them removed.
I know that my daughter struggles in your xxxxx class greatly, however I also know that she attends class daily, takes all your tests and does all her homework. How is it possible for her to be failing? Don't you think that there is something wrong with this picture? What is the point of showing up at all, seems to me the grade would be the same! Maybe she is really that stupid, or maybe she just doesn't understand xxxxx and needs some extra help. At the beginning of the year you said that you don't want the kids to run out and get tutors but I am told by both of my kids that you are not there before or after school and that it is hit and miss during lunch, even when they ask if you are going to be around for help (I doubt this is true, but it's what the parent wrote--Darren). She is also in xxxxx and gets tutoring in that class for your xxxxx class, I have instructed her to go to the library for tutoring after school Monday through Wednesday. xxxxx cannot fail your class, it is unacceptable on both of your parts! What are we going to do about this problem?
I want to fisk this letter, sentence by sentence; I really do. I mean, just reread the first two sentences: My kid shows up, does homework, and takes tests--how can my kid be failing? Ugh!
If I wanted to be kind, I could point out that at least the parent is concerned (before report cards came out!) and is trying to help his/her student, but the tone and content of the email just don't allow me to be kind. This parent is frustrated, and understandably so, but this is not how mature and rational adults communicate with each other.
