Isolation is good and bad, with no one to hear your screams….
The number of murder/rapes in the countryside during shtf events is deplorable.

But basically, as a good neighbor, remind them that the snow does fall, trucks don’t always arrive, bad things happen.

My home town never had a tornado hit, until it did.
Blizzard of ’81?
Denver in ’94?
People run/slide off the road.

Without skills? Trainable.
Invite them to the home canning class where everyone goes home with a couple jars of homemade soup. For those days when they don’t have time to cook/emergencies.

Start slow, they may end up your best help.
