Which Rules to Obey?

I watched a Dad and several youngsters hop into the hot-tub at our gym recently. They dropped their towels right by the sign that reads "No children 12 and under allowed in the hot tub!" Both kids looked to be five or six years old. Being a parent can feel like being under a 24/7 microscope sometimes, and this situation made me think about what we teach our children about rules and the truth.

Telling a "white lie" is accepted as part of navigating society. We cut corners a bit here and there to ease potential rough spots in relationships. What was the father in the hot-tub teaching his kids about rules? Are some "made to be broken" like athletic records? I can't imagine telling my children to obey traffic signals and speed limit signs, while I keep one eye on the road and the other on a radar detector. I can't imagine letting my kids into the hot-tub before they're twelve years old. If they see me flaunt one rule, that will confuse them about which rules can be bent or broken.

That said, I hope that sixty years ago I would have insisted that my boys give up their "front of the bus" seats to an African-American woman, regardless of where on the bus that woman was "supposed" to sit. Some rules were made to be broken I guess. How do you explain to your children when a rule doesn't make sense? Or when a rule, like the hot-tubs at my club, makes sense for some people but not for others?
