Contrary to the perception of Anon Whathishername, my granddaughter herded me into her corral.

If that were true you'd be speaking of your granddaughters memories rather than the repetitional history of your eighty years and your personal opinions regarding those eighty years.
BTW, I usually do not respond to people who are obviously not interested in what I have to say; to comments which I do not understand, or to those who simply want to pick a fight.

Of course you do. You respond by saying you don't understand and from your inability to understand create the illusion that the misunderstanding is the fault of the other person and that person is trying to pick a fight.
A person of eighty years is often close minded, a dog incapable of learning new tricks.
