Amen, preach. Hallelujah!
Seriously, there's nothing wrong with a small sermon now and again. Sometimes the youngsters demand it.
I prefer a more Socratic style.
Case in point: I asked him, not long ago, "If you have to rely on another person for your food, housing, healthcare, education and retirement, are you truly free?"
"No."
"If you demand another person provide for your food, housing, healthcare, education and retirement, are THEY truly free?"
The look in his eye when he realized the conclusion was most telling.
