Dear student, 

Prerequisites are, in fact, not real. Especially for you. You are special and do not need the experience or education the department had decided was in students' best interest before taking a class. So feel free to disregard and take your anger and frustration out on me because you knew this, and I did not. I apologize for the miscommunication and submit my resignation as your advisor, effective immediately.


Sincerely,
Me
