I've always felt that one of the most important tasks for a parent is to teach their kids to not be gullible. I routinely work on such training with my kids. In fact the other day, I was way into the story about how Los Angeles schools, while not getting many snow days, do get closed for bad hair days. Unfortunately, while my daughter was well into the "realy?" stage, my wife piped up with "They do not!" cutting me off at the knees.
So parents, take this as a warning. Train your kids in anti-gullibility before they make a fool of themselves publicly.
