Just a correction, to name the person in charge of the moment-to-moment management of the classroom.
Lemme repeat... parents can't cop out on their responsibility of authority! It's turning the job of nanny over to the teachers that has brought on much of the moral rot and destructiveness of today's children. Yes it would be a good idea for teachers to explain at the start of the school year that the pledge is not required if the parents or guardians do not wish it, but to make this the main point is to miss the main point.
