Martin and Sylvia's next-door neighbors, the Browns, are clearing out their barn and organizing a tag sale. They invite Martin and Sylvia's family to join them. Martin enthusiastically chooses toys and books he no longer uses to donate to the sale, but Sylvia is troubled by the idea of giving her old things away. In the end, she is surprised how much fun and satisfying it is to see other children love her things as much as she did.
