阅读下面短文，根据所给情节进行续写，使之构成一个完整的故事。
Three boys and three girls were going to the beach. When they boarded the bus, they were carrying sandwiches and wine, dreaming of golden beaches. Suddenly, they noticed Vingo. He sat in front of them, eyes fixed upon a photo, completely in silence.
Deep into the night, the bus pulled into Howard Johnson’s, a service area, and everybody got off except Vingo. The young people began to wonder about him. When they came back, one of the girls sat beside him and introduced herself. “Want some wine?” she said. He smiled and took a swig from the bottle. He thanked her and became silent again.
The next morning, they awoke outside another Howard Johnson’s, and this time Vingo went in. The girl insisted that he join them. He ordered black coffee and some cookies. When they returned, the girl sat with Vingo again. After a while, slowly and painfully, he began his story. He had been in prison for the past four years, and now he was going home.
“Are you married?”
“I don’t know.”
“You don’t know?” she said.
“Well, 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 stand it, if the kids kept asking questions, and if it hurt her too much, she could just forget me. I’d understand. ‘Get a new guy.’ I said. She’s a wonderful woman. I told her she didn’t have to write me. And she didn’t. Not for three and a half years.”
“And you’re going home now, not knowing?”
“Yeah. Well, last week, when I was sure the parole (假释) was coming through, I wrote her again. We used to live in Brunswick, and there’s a big oak (橡树) tree just as you come into town. I told her that if she didn’t have a new man and if she’d take me back, she should put a yellow handkerchief on the tree, and I’d get off and come home．If she didn’t want me, forget it — no handkerchief and I’d go on through.”
“Wow,” the girl exclaimed, “wow.”
She told the others, and soon all of them were in it.
