I've been following the various meetings and discussions about how to safely reopen schools, and the one thing everyone agrees on is that there really isn't a "best" way to do it.  Whatever happens, though, whenever students, teachers, and staff are back in schools, I believe it's vital for everyone to wear masks.  I've taught in elementary schools for 14 years, and sickness spreading throughout a classroom/the entire building is simply a fact of life in an environment like ours.  Since we know that it WILL happen, let's please take steps to minimize its extent and the risk to not only everyone in the building, but everyone who the people in the building come in contact with, by having everyone wear masks while we're there.
