Adolescence will seem, for most parents, like the time of the great uprising. Herein, all the moral values you have taught and modeled will matter the most. The opposite is also true. The values you failed to teach and model will come back to haunt you.
As in the case of one mother who asked me during the question and answer session, after I gave a speech, what she should do since she had never set down any rules for her child. The short answer: set some rules and hang on for the ride. The long answer: WW III is about to begin at your place. Good luck.
