Last Halloween, I dressed up like a teacher — not exactly an alter ego; I have a certificate — went to the local high school, and substituted in Family & Consumer Science.
There was a small ruction in third period; the principal and I discussed it amicably, and I barely gave it second thought. However, a couple weeks later, I received a letter informing me he was removing me from the sub list! Explanation (from said letter): he “visited with the class,” and the “interactions between yourself and the students were not such as meet our expectations for substitutes.”
A parent reported that a student had videotaped me on his cell phone. So, no doubt if there were a hint of unethical practice — singling a child out for ridicule, touching anyone, or making unreasonable demands — either on the video or in student testimony, my infraction would have been fully detailed.
