They  46   work at a carnival instead of in a store or something". "Come down tomorrow and  47  them yourself," he said.
So the next day I went to the carnival and to the exhibit he had  48  me to. The twin brothers   _49  out to be Siamese (连体的) twins, joined at the chest. He hadn't thought this  50  was noteworthy enough to mention. When I brought it to him, he said, "yes, I  51  that too.

Today, Joe, one on the fight, made me spaghetti (意大利面条) for lunch. "
What others see first in a person is not what a child considers  54  . Where I saw Siamese twins, he saw people having difficulty buying clothes that fit, and young men who were good cooks. It was a   _55  I have thought about many times over the years.
