First, allow me to again express my condolences for your loss and Hogwart's loss. It was a lovely ceremony and I was honored to attend. The late headmaster will be missed greatly. He made a great impression upon me, when I attended Hogwarts that year of the Tri-Wizard Tournament, and the memories I have of Hogwarts are much cherished.
I wanted to speak with you, but I thought it best to do so at another time, or perhaps in person? I am currently on a medical leave from my profession, but my need to stay in touch with the Quidditch game is great and I would like to offer your school my services. Perhaps I could come to the school as a volunteer coach for the four teams? Please, Headmistress, you would be doing me more of a kindness, to let me instruct your students.
I am currently working at the Ministry, in the Department of Magical Transportation should you need to contact me further. I look forward to your decision.
