I had thought that Jefferson and Adams were bitter political rivals and so was very surprised to read this. With a quick check from Wikipedia, I learned that, "[after being] defeated for re-election by Thomas Jefferson and retir[ing] to Massachusetts, he later resumed his friendship with Jefferson."

Anyway, I like the quote for rationality purposes as well as for the fact that I now have a start on quote-mining if I ever need to write terrifying Jefferson/Adams shipping fanfiction. Why I would need to do so is nonobvious to me right now, but it is one of many contingencies for which I am now prepared.
