In only about 200 words, author P.K. Hallinan expresses the love and respect all children have for their grandmothers in My Grandmother and I. The opening line, 'My grandma and I are the greatest of friends' sets the tone of this poem from child to grandparent. And the conclusion, 'We're best friends forever, My grandma and I!' expresses the special bond that exists between every grandchild and his or her grandma.
