     Robert lives in a small town. Five years ago, when he was nineteen, he finished middle school. He didn't

like any subjects except playing when he was at school. Of course he learned nothing and the bosses wouldn't

use a man like him. He has to stay at home, but doesn't do any housework, only watches TV or lies on bed. It

makes his parents angry. They want him to study something, he always think it difficult and doesn't listen to

them.

heard the publishing house pays the writers a lot. He became interested in it. As soon as he got home, he began
