So I (or someone like me) went back in time and surreptitiously changed the words without the Framers' knowlege, giving the appearance that they chose distinctly different words in some cases from the words they chose in others. Dang, I wish I could find that time machine so I could go back and invest some startup capital in Microsoft, and Yahoo, and Google, not to mention short-selling GM and Citigroup.
