Dear XX University,
Your fellowship of the School of XX for the Fall 2042 semester has now been received. I regret to inform you that after careful evaluation and discussion with my Dad, your admission and financial aid have been denied without hesitation. Bazinga! Hia Hia Hia Hia!
This year I receive nearly 2000 offers. As I can choose only one, I must deny a majority of graduate schools, even some very excellent ones. In the case of most offers, there is no single reason for denial; consequently, I cannot be more specific as to why your offers were denied.
I realize that my decision will disappoint you and hope that it does not discourage you from keeping your dignity and courage to keep walking. My dad and I wish you our very best in your future endeavors.
