The day finally came, when I had to leave the warm home where I’d grown up. I ran to the back yard, as tears came up from my heart. Suddenly I    36  a hand rest on my shoulder. I looked up to    37  my grandfather. “It isn’t    38  , is it, Billy?” he said softly.
He gently    39   my hand in his, and then we walked, hand in hand, to the front yard,    40   a huge red rose-bush sat alone.
“What do you see here, Billy?” he asked. I looked at the flowers, not knowing    41   to say, and then answered, “I see something soft and    42  , grandpa.”
He pulled me    43  . “It isn't just the roses that are beautiful, Billy. It’s that special place in your heart that makes them so.” “Billy, I    44   these roses when my first son was born. It was my    45   of saying ‘thank you’ to God. I    46   to watch him pick roses for his mother. Then, as a young man of only 20, a terrible war robbed him of his life.” Grandpa slowly stood up. “Never say good-bye, Billy. Never    47   to the sadness and the loneliness. Instead, I want you to remember the joy and the    48   when you first said hello to a friend.”
A year later, my grandpa became very    49  .Then all members of the family
were    50   back, and I returned to the old house. When it came to my    51  , I took his hand as    52   as he had once taken mine.
“Hello, grandpa,” I    53  .His eyes slowly opened and said, “Hello, my friend.” With a brief    54   he died. Suddenly, and truly, I knew what he had    55   about never saying good-bye — about refusing to give in to sadness.
