Her problem? A student was mad at her. I forgot all about this because it sounded so unimportant. I was mad that I wasted some of my best sneaky teacher moves to get that non-story. A few weeks later this teacher came up in conversation. Apparently she was still upset because her and a student were "having a fight." Is this real life? You are a teacher, not a kid. You don't have fights with kids. Why are you so upset that the kid is upset. Later she won't be. Get on with your life. You are supposed to be the adult and the teacher. Trying to be friends with the kids only spells disaster for you, your classroom, and your students. Stop it childish teacher. You're upsetting everyone.
Am I being harsh? Maybe, but this is a serious gripe. I have a confession for everyone here. I stopped having 16 year old friends when I graduated high school. I'm glad I finally said that out loud. I hope none of you think less of me. I have zero interest in becoming friends with a teenager now that I'm an adult. It doesn't sound fun and, quite frankly, it wasn't that much fun back then. I just didn't know enough about life to realize it.
