I’m a teacher and I make mistakes all the time.
I usually stop class and say, “Wait a minute. I think I just learned something.”
The kids look at me.
I say, “Apparently, I’m human. I’ve made a mistake. Wow, I thought I was perfect. Well, there you go, dears. Even your teachers…including me, make mistakes and a wrong sometimes.”
Of course, all of this is sarcastic and so forth. The kids are usually very understanding. If I misplace/lose something, I tell them and usually for the next day or so, I’m more lenient with them about forgetting things and losing things.
I use my errors to illustrate that no one is perfect, but also to point out that I am generally responsible and I don’t forget everything everyday.
I teach 7th grade, a key year in my opinion for the kids to start becoming more responsible.
