I once was in charge of some Civil Air Patrol cadets on a camp out and one cadet brought her little brother because no one else could look after him. I found him with a lit match against the side of a ten inch thick log trying to start a fire. As an adult with children of my own, I tried to explain why he could not get it hot enough, needed small sticks, etc, with no result. His sister saw the discussion, walked over, smacked him side of the head, and yelled, "Stop it stupid". His response, "I almost got it".
