Parents know the feeling of not really being listened to by their children, but it's not just children that have that issue.  In the gospel reading from Mark 10, James and John show that they really haven't been hearing what Jesus had to say and so they make an incredible request of Jesus.  But Jesus uses the opportunity to teach the sons of thunder, as well as the rest of the disciples, why He had come and what true greatness really looks like in His kingdom.
