Stuart Ample and Eric Marshall have an unusual gift for listening to children, and for picking out the memorable thought and the unique turn of phrase. They compiled <i>Children's Letters to God</i>, which has 1,110,000 copies in print. And in <i>Grandma, Grandpa and Me</i>, they celebrate what kids have to say about their grandparents. <br><br>"My grandma gave my mom a very beautiful ring and someday she is going to give it to me and someday I will give it to my daughter. That's the way you make history." --Brooke, 9<P> "They never forget your birthday. They never forget what you want. If you feel bad, they know how to make you feel good." --Emily, 9
