On their weekly walks, Jill and her Nonno love to play with words. “Hummingbird,” says Jill. “Sugar-drinker,” says Nonno. “Seaplane,” says Jill. “I do see a plane!” replies Nonno. But one day, Jill notices Nonno is acting differently. He isn’t interested in their usual game and simply repeats what Jill says. When Jill asks her mother what’s wrong, her mother says Nonno isn’t running out of words, he just can’t always find the words he’s looking for. Is there anything Jill can do to help?
