   This picture shows the importance of Father-Son bond becuse andy and his son are close and would do anything for eachother just like Eli and his father. Throughout the book Eli watches out and takes care of his father. Eli felt as if he couldn't servive without his dad. After Eli see's some of the things that the sons would do to their fathers made him feel guilty as if he wasn't taking good enough care of his dad. Without eachother they probably would have died sooner.
