#13: Too Much Information
Remember when you were in your early years at school, and your teacher would mention something about their private life, about her husband, kids or pets? It was always a little awkward to think about your teacher as a real person and not just a heartless robot.
We imagine it must have been incredibly shocking, then, for this group of students to hear their teacher sing hateful songs about his ex-wife. Clearly, this teacher had some issues to work out, but therapy may have been a better environment for that, not a 7th-grade study hall. Besides, he sure wasn’t setting a very good example on maturity.
