Just make sure that you and your family are better protected than your neighbor.
You can't change who is your neighbor,
but you might want to encourage him to learn how and when to "prepp".
It may have been a flippant comment, on the other hand, he may be envious of your wisdom.
The Scriptures are have numerous warnings about jealousy and envy.
Better to encourage a friend, than to develop a potential enemy !
Well I live in a retirement community. If ever confronted with a catastrophe like the poor folks in the Bahamas, with a complete break down in services and law, people are going to drop like flies.
Actually the repeated hurricanes warnings of the past few years has turned people into being less complacent and more prepper.
