When I was in the earliest grades we said the School Prayer along with the Pledge. All I remember was that it ended with "our parents, our teachers and our country," not overly religious. But when I was still in elementary school they replaced it with "a moment of silence," when we were told we could pray if we wanted. Of course that was confusing for us kids, but then that disappeared too and nobody missed it.

I'm just guessing that there was something passed here in New York related to "the separation of church and state," I certainly never knew. Maybe somebody objected? I lived in a fairly diverse community. However, that was obviously decades ago, so how is this permitted in 21st century America?
