This self-centered response is more in keeping with the old Jacob. Children, even grown children, need a parent's advice, sympathy, and understanding. Rather than this expression of scorn and condemnation on Jacob's part, it seems that some sense of a shared burden would have been more appropriate. It's not an easy thing to be a good listener. You have to overcome the tendency to think that it's all about you.
Humility plays a major part in sustaining a life dialogue.
The ability to understand the needs of your counterpart is essential. The sons of Jacob are experiencing their own sensations of pain, fear, and regret. If he meets with disaster on the journey you are taking, you will send my white head down to Sheol in grief. While it is true that age often increases egocentric behavior, members of the younger generations are often just as guilty. When you appear immortal in your own eyes, everything is always about you.
