My brother Doug sent me an email with a link. This gives you a hint of what it is about.

Professional trappers don’t catch fast-breeding and destructive feral pigs using hunting dogs and guns, or in little traps one or two at a time. The wily pigs quickly learn to evade humans after such fleeting contacts. So how do the pros trap entire feral pig herds, eliminating them all, from granddads to piglets, in one go?

They feed them, most generously. They kill them with kindness.

…

The moral of the story: If it looks too good to be true, it probably is. Don’t go inside the “free corn” pen, not even when all the doors are open. Free food is as dangerous as the sirens’ song to ancient mariners. It is all too easy to get used to being fed, and then to miss the exits closing one at a time.

I read the entire post and all the comments. Most will stop after the first parable which is probably enough to get the point across. Just to make sure read the second one also.
