Got this email from the head of year today, I haven't actually asked her about my appointment yet so it went out to everyone. I quote:
"Can I remind all students that non-urgent appointments for dentists, opticians and doctors need to be made outside of lesson time. I am very worried to hear that a student missed a lesson because of an optician’s appointment. This is not acceptable. We need to know of all absence beforehand. It needs to be approved by me to be authorized.
Remember we are monitoring your attendance."
I really don't want to tell her now...
