Successful societies have historically taught their youth certain behavioral axioms, one of which lies in the fact that undisciplined indulgence in that which is defined as pleasure must result in a failed lifestyle. (See the writings of Aristotle and Jesus).
In relationship to that axiom, the child should repeatedly be advised that successful marital relationships are dependent upon the “compatibility” which must exist in that union, the absence of which is now evidenced in our society’s 50 percent (plus) divorce rate.
Given the nonsense portrayed in the typical movie (and the blithering of fools, not a few of whom boast the title of Ph.D.) suggesting that sexual activity and physical appearance are all important, the parent should seize appropriate opportunities to convey the real facts of life to his or her children. One doubts that the distanced church sermon adequately conveys a clear message regarding these matters.
