I felt the same. The actual detention got postponed for several weeks, since she had more important duties to attend to. When it finally happened, we played chess together and talked about movies.
She made me promise I wouldn’t tell anyone, but since she passed away over 25 years ago I don’t feel binded by it anymore ;)
In the sixth grade I got my first detention ever because I picked up my baseball cap.
We were on a field trip and we went to visit some museum in the capital by train. While we walked back to the train station, our teacher stated that “no one is to step out of the train before her permission or they will get detention”. I was the last to get on the train and my cap hit the backpack of the classmate in front of me and fell out of the train doors. I instinctively turned around, leaned out whist holding onto a safety bar and picked my cap. And stepped back on board.
I was a calm kid and had never broken any school rules or gotten into any trouble whatsoever. So when my classmates saw me putting one feet outside the train they simply flipped: “TEACHER, LORINDÓL STEPPED OUT OF THE TRAIN! YOU’RE GETTING A DETENTION!”
I was utterly dumbfounded. My “friends” had betrayed me and the teacher was approaching and looking angry. With tears in my eyes I explained what had happened and reminded her that we still had more than 10 minutes until the train doors would even close. Her face went from angry to sad and she silenced my heckling classmates with a few strict words. She told me that we would discuss this when we were back at school.
When we got back, everyone else got to go home and the teacher asked me to our classroom with her. “Lorindól, I’m very sorry. I have to give you detention because you did step out of the train, even if it was for all the right reasons. I understand you acted instinctively and did not mean to break any rules. But I must keep my word or it will lose it’s meaning. As stupid as this sounds, the purpose of this detention is not to punish you. It’s purpose is to show the others that my word is the law in this classroom, with no exceptions. I hope you can understand why I must do this.” I thought about it for a while and said that I did.
When I told my parents about the detention my dad couldn’t stop laughing. “You finally get a detention and it’s for NOTHING!”
Mom was so angry that she wanted to call the teacher and make her call the detention off. I managed to talk her out of it and didn’t hold any grudge against the teacher. I learned a lot about the world of adults that day.
