4Lucy and her grandfather are the focus of this poignant and warm story that teaches that wrinkles are badges of happiness rather than signs of age. Lucy asks Granddad, " Why doesn't your skin fit you? It's all crinkly," to which he replies, " Those crinkles are called wrinkles," each of which he got when he smiled especially big. As Lucy traces Granddad's joy-filled face, he describes his memories and shares the cause of each line-- his wedding day, Lucy's mother's birth, precious moments from her childhood, and Lucy's birth, among others. Beautiful drawings recreate each thoughtful memory, and the recollections showcase an intimate bond between the two generations.
