I had a kid who threatened to kill me one year because I gave him an F. Another teacher caught one of my students writing 'Kill Mr. Vallee' in his weekly planner in the section labeled 'Weekly Goals and Objectives.' And the school was freakin' out. They didn't know what to do about it. They kept asking me if I felt threatened, and I'm like, 'Why? This kid hasn't met any goals in his objectives all year.'
