Three boys and three girls boarded the bus to Fort Lauderdale, dreaming of golden beaches as the gray cold of New York disappeared behind them. They noticed an old man, who sat in front of them, dressed in a plain, ill-fitting suit, never     , and his dusty face     his age.
He was    in his seat like a stone, and the young people began to      about him, trying to     his life and his age. Deep into the night, outside Washington, one of the girls went up to him and introduced herself. “Want some wine?” He took    the glass and drank.
Slowly and       he told his story. His name was Vingo, he had been in     in New York for the past four years, and now he was going home. “When I was in prison I wrote to my wife,” he said. “I told her that I was going to be away for a long time, and that if she couldn't     it, if the kids kept asking questions, if it     too much, she could just forget me, I'd understand.”
“Last week, knowing I would be     , I wrote her again. We used to live in Brunswick and there's a big oak tree just as you come into town. I told her that if she would     me back, she should put a yellow handkerchief on the tree, and I'd     and come home with her. If she didn't       me, forget it, no handkerchief, and I'd go on through.”
　　“Wow,” the girl exclaimed. She told the others, and soon all of them put their faces against the window, waiting for the       of Brunswick.
Then Brunswick was ten miles, and then five. Then, suddenly, all of the young people were up out of their seats, screaming       , all except Vingo. Vingo sat there     , looking at the oak tree. It was almost        with yellow handkerchiefs, 20 of them, 30 of them, maybe hundreds, a tree that stood like a huge flag of      , blowing in the wind. As the young people shouted, the old man rose and      his way to the front of the bus to go home.
