The 16th is TWO centuries removed, and almost THREE , from where you stuck the Revolution and the writing of the Constitution. I'd say that that was a far cry from a " little " mistake. And no, I am not " perfect " ; however , I don't make such howling mistakes. If you don't want to be called on them, be more careful what you type. If you don't want to prolong this agony, allow the subject to wither away, by keepng your mouth shut. That's how it works here.
Oh, and DO feel free, to correct me, should I ever make such a dozzy ! : - )
