Bartholomew was an old man, and when Nelly was a baby, he took her for walks in her stroller every day. As she grew older, he helped her learn to walk and skate. They were special friends. But as Nelly grew older, so did Bartholomew. One day, as he went out for a walk, he fell down the stairs and had to go to the hospital. When he came home, Bartholomew was in a wheel chair. Now it’s Nelly’s turn to push Bartholomew.
