BJ and his wife had dinner with a family they know yesterday. One of the family's kids was talking about how he was going off to college this weekend with just a tank of gas and 30 dollars. The kid was trying to figure out how he was going to make it to school without getting any additional help because his mom won't even help him make sure he has enough gas to get to the school. The dad suggested that the mom wants to teach the kid a lesson. What lesson is being taught here?
