“Were you flying the Confederate flag?” “No. I think there were two or three that was, but they took them down as soon as we parked,”
Maybe the school should stop worrying about flags and concentrate on teaching grammar.
While they’re working on grammar for the students, they could send the staff member that wrote the original statement about a “safe, learning environment” in for a brush-up on punctuation. The comma is unnecessary because safe is a modifier for learning. If it is supposed to be a series, then the proper use is “safe and learning environment” since it is a series of two items.
