The problem is not that it's confusing but that, because the rules exist and set our expectations, we mentally trip over violations of them. We stop absorbing what was intended to be communicated and have to back up and try again. I don't disagree that changing the rules would solve this, but we haven't done that. So in individual instances of written communication which each of us does have the power to affect, it's on the writer to ensure the reader has no unnecessary trouble. I could wear boots inside your house, but I'd rather you clean up the Lego.
