Same here!
I don't know about other schools,but at my Daughters Middle school and my sons High school it holds true!
It also holds true at the Elementary school both attended when they were younger!
In fact the teachers and school administrators encourage it,at least at those schools!
That's great!
I only have the experience so far with the elementary school, but friends with older kids say it continues up into the middle and high schools here.
We moved from Delaware to Virginia in part because the district we lived in fits every stereotype that can be used about public schools.
