I was thinking about using one of the numerous generic rejection letters I got from schools and retooling it as my withdrawal letter:
To The Admissions Committee,
I have completed my interview season and have seen numerous medical schools, and I regret to inform you that I will not be bringing my talents to your school in the Fall of 2017.
I realize that this decision may come as a disappointment to you. As you may know, I interviewed at a great deal of medical schools however only one medical school could be chosen as my place of matriculation. I do want to assure you that I considered your curriculum, facilities, and reputation carefully and thoroughly before my decision was made. These decisions were difficult to make due to the sheer volume of qualified schools. Please do not take this withdrawal as a slight to your strength as a medical school.
Thank you for your interest in me as an applicant and I wish you luck in filling your class for the Fall of 2017.
Sincerely,
Machete Fred
PS I am interested in applying to ur podiatry school
