I had just such a conversation with a libinlaw the other night.
I asked her how it could be that they insisted they were right then, and insist they’re right now.
How did they get reality to change, since they are so obviously infallible that we have to change our behaviors and lifestyles according to what they absolutely know to be right at the time... ie, Global Warming.
LOL... Good for you. I don’t even bother to talk to libinlaws anymore.
