O Wise One??

I have a student in 7th grade who never calls me Miss Gray. For the longest time, it was "Teacher". I told him I would rather be called Miss Gray, but still, it was "Teacher". I finally told him I was going to call him "Student" and that seemed to get rid of the "Teacher" comments. Although now, his new game is to figure out what new names he can call me. He calls me teacher, I call him student. He calls me professor, I call him scholar. Etc.
The other day, he deicided to call me "O Wise One" in the middle of class. I asked him if that meant I could call him "O Foolish One." That quickly ended my "Wise One" days! He's now moved on to coming up with the next name :) Middle Schoolers...I'll never understand them, but sometimes they do make me laugh!
