I have two little granddaughters. One minute theyre squabbling over a toy or jostling for attention, and the next minute, theyre hugging and kissing each other. Its a constant back and forth of friend and foe. Im watching them forge a relationship that will last all their lives. I hope my granddaughters develop the closeness that Ive always enjoyed with my two sisters. Theres nothing like the love of a sister. It grows out of a shared history of funny, stormy, trying, joyful experiences.
