Bob and Bobby are best friends. They also happen to be related: Bob is Bobby's grandfather. They do everything together. They play with blocks, they talk, Bob even taught Bobby how to walk. Then something terrible happens to Bob. Even though it scares him, Bobby decides he needs to help Bob get better.
I am such a sucker for these types of stories! It is a simple story of the love and caring a kid and a grown-up have for each other. If you have ever had a special relationship with an older relative (grandparent, aunt, uncle), you will really love this story!
