My own children, when they were young, went to private Montessori schools, and didn't have to recite the pledge everyday. In one case, this led to some emotional distress.
My daughter Noelle was in a summer day camp that was provided by the Chicago Park District. On her first day, she came home very upset. She was embarrassed that she didn't know "the Jesus prayer." She told us all the children had been required to say "the Jesus prayer" but that she didn't know it. We puzzled over this, finally figuring out, of course, that they were saying the Pledge of Allegiance at day camp. I guess she heard the "God" part, and probably misconstrued "Pledge of Allegiance" to be "Blah blah blah Jesus."
Rhyme of the day:
I love the flag,
But I'd rather not drag
Deity into my fealty.
