Those of us raising teenagers are all doing our best to teach our offspring not to participate in risky behavior. We promise rides home from parties with no questions asked. We talk about safe driving practices, seatbelts, safe sex (OK, some of us don't talk about that), not to trust people they "meet" on the Internet. You get the idea. Being safe, or at least making smart choices about risk, is one of the key attributes of mature behavior. But every day, in the business world, we aid and abet risky behavior.
