Teaching is not for the weak of heart. Kids are addicted to disrupting class and making their teacher's jobs as difficult as possible. I remember being a student and feeling incredibly frustrated when I was in a class full of "bad kids." Three or four disruptive students could ruin a class for everyone, especially the teacher.
If you're an elementary school teacher, there are some simple strategies to get kids to be quiet: for instance, "put a bubble in your mouth." Whoever came up with that is a genius who should get an honorary Ph.D. in education. Once you get up to middle and high school, putting a bubble in your mouth won't cut it. Older kids who won't listen need tough love, and teachers are prepared to give it to them. This week, teachers on Reddit shared the harshest things they've ever said to their students, ranging from hilarious jokes to sick burns.
