Yes, indeed. I wrote a paper on drug use (not abuse, that is recreational drug use that doesn't lead to addiction) and found that the only real consistency in people who become addicted is a history of alternating spoiling and neglect... apparently that leaves you not having enough of anything till you have too much of it. It was an interesting research topic.

Whereas, one of my sons was BORN civilized. Didn't have anything to do with what a completely nice person he is...
