A visit to New York City on the day of Grandpa's birthday holds many adventures for Gabby and her mother. Their plans include a haircut at a department store, lunch at a cafeteria counter, and skating at the park with Grandpa. Gabby can't wait!
When Gabby spots a very grown-up-looking girl on the train with perky short hair, Gabby gets an idea about her own haircut. . . . Is Gabby ready for such grown-up hair? What if Grandpa doesn't like the new haircut? What if he doesn't like his present? There is such a lot of waiting to do before Gabby gets her answers but finally she does, and Grandpa gets a wonderful birthday surprise.
