I hardly remember my grandmother.She used to holding me on her knees and sing old songs.I was only four when she passes away.She is just a distant memory for me now.I remember my grandfather very much.He was tall, with broad shoulder and a beard that turned from black toward gray over the years.He had a deep voice,which set himself apart from others in our small town,he was strong and powerful.In a fact,he even scared my classmates away during they came over to play or do homework with me.However,he was the gentlest man I have never known.
