Back in 1978, Lidia Mostovy was chosen to deliver the valedictory address at the 99th commencement of Frank H. Morrell High School, so she decided to give it in Latin. Her speech began: "Olim Alexander Magnus dixit: 'Meis parentibus vitam debeo, meis magistris, vitam bonam.'"
She explained that she "wanted to add dignity to the graduation exercises and... draw attention to the high school's Latin program. 'A lot of people ask why take Latin — you're not going to use it. So now I will.'"
Since I took Latin throughout high school, and even participated in our high school's Latin play, I'm sympathetic to what she did. And I guess it probably wasn't any more or less boring than any other high school valediction, just because no one could understand it.
With just a little ingenuity and knowledge about the kids it is still possible to keep order in the classroom. One well read math teacher in France came up with a real gem that seems to be working for him. Having read all the books in the series he informed the class that he would post 'Game of Thrones' spoilers if order was not maintained. Afterwards there was what one student described as a "religious silence". Well done sir, well done!
