My name is Lucy and this is my grandfather. His name is Tim and he is my best friend. My grandfather is 64 years old and he is retired now, so he has much time to be and play with me. I love him very much and I know he loves me too.

    He lives with me, my father, my mother and my brother Kevin. We live in a big house. My grandfather is a very tall and strong man! Can you see me on his shoulders (肩膀)in this picture? He is really strong! My grandfather always knows what I want to do or to eat or what I feel inside! When I am sad, he makes me laugh with his funny faces. Every night before I go to bed, my grandfather tells me stories, and he even sings for me!
