It surprised me when my eighth grade chorus teacher, Mr. B., announced that he expected next semester's eighth grade chorus class would be a difficult one.
Near the end of the semester, he announced to our class, "All of the troublemakers and difficult kids I didn't have this semester, I'll have next semester." He then read off the names of everyone in that class.
I still wonder if anyone took that information out of context, as middle school students sometimes do. I wouldn't have put it past some students to tell individuals in the second semester class, "Mr. B. said you're a juvenile delinquent."
