     "Frank!" I cried in astonishment. He couldn't   2 , as I knew, but all the time   3   his foot against mine.
     My   4 raced back more than thirty years to the   5   days of 1941, when I was a student in London.
The   6   was an air-raid shelter, in which I and about hundred other people slept every night. Two of the
regulars were Mrs. West and her son Frank.

has. His " 12 " consisted of rough sounds-sounds of pleasure or anger and  13  more. Mrs. West, then about
75, was a strong, capable woman, as she had to be, of course, because Frank  14  on her entirely. He needed

     One night a policeman came and told Mrs. West that her house had been flattened by a 500-pounder. She

     When that sort of thing happened, the rest of us helped the  17  ones. So before we  18  that morning, I
stood beside Frank and  19  my right foot against his. They were about the same size. That night, then, I took
a pair of shoes to the shelter for Frank. But as soon as he saw me he came running and placed his right foot
against mine. After that, his  20  to me was always the same.
