There’s an old(er) guy at the coffee shop with whom I often indulge in solve-the-world’s-problems bull sessions.
He knows a lot about a lot of things, but as with any far-ranging morning chat with the boys, topics always come up that some or all of us know nothing about.
Most of us just bluff and offer our comments based on something we think we mighta heard somewhere.
The old guy often says “I really don’t know” and sits silently while we keep spouting off and pooling our ignorance.
But when he speaks, we all listen.
I consider him one of the wisest people I know.
