I knew that I didn’t believe in God when I was around 7 and my parents were good about it, stopped sending me to Sunday School etc,. I wouldn’t bow my head (is that a rule, are there prayer rules?) but I would respect others as it doing me no harm.
Just had a text from Mrs. She spoke to the head as she was at the gate this am. Apparently it sounds like like it is not the policy she implemented and she will email a reminder out.
