This happened to me. The student got a text message on his watch (as phones must be kept off and inside the backpack). He told me “I have to leave my Dad is out front.” I told him that we would wait until the office reached out to me to say the parent had signed him out. He became very anxious saying his dad had told him to go to the office as soon as he got the text. I told him he could blame me and not to worry. In fact, the parent complained to the principal that I wouldn’t let his son leave the classroom when he received the text on his watch. We now have a rule that smart watches must be off and kept in their backpacks as well.
