I'm Choosing to Feel Loved!

Last year the university enforced a new policy that students may no longer call professors and staff by their first names. With a three syllabal last name, I was often called Professor M. One student, however, decided that even that was too long and he began calling me ProM instead. It wasn't long before almost all the students were calling me ProM. It didn't bother me, I don't think it was ever said rudely and I can think of much worse things to be called.
This year I find myself still being called ProM, only this time by former students, new students, the office ladies and even a few fellow professors. I suppose I should feel loved?
Yesterday I went down to the school to make a few copies and do a little cleaning in my office. I went into the nursing student lounge to put some things in the student mailboxes. As I looked up at the white board, I saw this...

I suppose I should be glad that it didn't say "ProM Sucks!"
