"I recently watched a Netflix show called 13 Reasons Why which delves deeply and unabashedly into issues many teenagers deal with but are unwilling to discuss, such as suicide, cyberbullying, and rape. One of the most interesting things I learned is that a teenager's hippocampus isn't fully developed, which is why they can interpret a negative remark or dirty look as lasting and eternal. It really helps me to have more patience and empathy with my more problematic students as I realize there are plenty of issues beyond the surface that I might not be aware of."
