There was a woman named Japan Atsuko Saeki living in the city of Fujisawa．When she was a teenager, she    of going to the United States．Most of what she knew about American       was from the textbooks she had read．“I had a        in mind: Daddy watching TV in the living-room, Mummy       cakes and their teenage daughter off to the cinema with her boyfriend．”
Atsuko   __to attend college in California．When she arrived, however, she found it was not her        world．“People were struggling with problems and often seemed       ,” she said．“I felt very alone．”
One of her hardest        was physical education．“We played volleyball,” she said．“The other students were         it, but I wasn’t．”
One afternoon, the instructor asked Atsuko to        the ball to her teammates so they could knock it       the net．No problem for most people, but it terrified Atsuko．She was afraid of losing face     __she failed．
A young man on her team        what she was going through．“He walked up to me and      , ‘Come on．You can do that．’”
“You will never understand how those words of         made me feel…Four words: You can do that．I felt like crying with happiness．”
She made it through the class．Perhaps she thanked the young man; she is not      ．
Six years have passed．Atsuko is back in Japan, working as a salesclerk．“I have       forgotten the words,” she said．“When things are not going so well, I think of them．”
She is sure the young man had no idea how much his kindness        to her． “He probably doesn’t even remember it,” she said．That may be the lesson．Whenever you say something to a person cruel or kind—you have no idea how long the words will    ．She’s all the way over in Japan, but still she hears those four        words: You can do that．
