Being a teacher is one of the most rewarding yet difficult jobs one can do; on the one hand, you’re helping to shape the next generation, and you get to help kids learn and grow. On the other hand, though, kids will be kids, and you’ll always have those one or two students who really know how to get under your skin.
Even the most patient teacher has their limit—they’re still human after all. Like this Japanese high school teacher, who apparently had it “up to here” with students spitting their gum out on the floor. So what did he do? Wrote a scathing note of epic proportions and pinned it to the wall for all to see.
