What exactly is "social distancing" ? It's a term we hear more and more "social distancing" but what does this really mean? Is this the politically correct way of saying "hey get away from me with your germs" ? Can't we just say "back off" or will that hurt peoples feelings? So now it's "please practice social distancing" seems awkward, but ok.
