<p>Many kids cause some cracks in the old heart as they live their lives their way making mistakes that make us cringe. I always say that if I had a weak heart, I'd long be dead. I just hope that the mistakes they makes, the disagreements about which path to take are not serious. When kids do truly harmful, dangerous, illegal things, and many of them do at one time or other, we are often helpless to stop them from making those mistakes. Any parent who has children who never indulged in such activities is so fortunate. I would pick my battles carefully.</p>
