Bartholomew and Nelly are not just neighbors, they're best friends. Every day, Bartholomew pushes Nelly in her stroller around the neighborhood. They especially like getting sprayed by Mrs. Pringle's sprinkler and going over Mr. Oliver's bumpity-bump-bump driveway. And when Nelly grows up and Bartholomew grows old their joy in being together continues, no matter what. For this story of two people, from two generations, shows better than most, what it truly means to be friends forever.
