Thank you so much for taking the time to ask your wife and to write that out. I am going to copy that into an email and see what comes out of it. I'm frustrated right now because this topic has come up a couple of times in the past and it's always the same request--talk to Alex and let him know to stop bringing things to school. What's the definition of insanity? Doing the same thing over and over again and expecting a different response. When I've replied to the emails and said take/throw away his stuff, that part of my email gets ignored. I'm going to run this (what you posted) by her and see what she says...
Tell your wife thank you very much for her input.
#1. If Mom &/Or Dad said don't, & he does, Mom &/Or dad must take corrective actions.
#2. The Teacher Must take control of her classroom, rather than sit behind a computer & send an email.
The old saying "If I got it at School, I knew I was going to get it at home", comes to mind.
Like someone else said, Team Effort.
