20．It was about eleven o'clock at night，and a large woman was walking alone，when a boy ran up behind her and tried to grab her purse.But the boy's weight and the weight of the purse caused him to lose his balance ，so he fell on his back on the sidewalk.
The large woman simply turned around，picked the boy up by his shirt front，and shook him until his teeth rattled.Firmly gripped and sweat rolling down on his face，the boy whispered， "I'm very sorry，lady，I'm sorry."But the woman just dragged him up the street.When she got to her door，she dragged the boy inside and turned on the light.
"You go to that sink and wash your face，"said the woman ，"Let the water run until it gets warm，" she said. "Here's a clean towel。I would take you nowhere.We'll eat，"said the woman.
"I wanted a pair of shoes，" said the boy."Well，you didn't have 1 o grab my purse to get some new shoes ，"said the woman." You could have asked me.""Madam？" The water dripping from his face，the boy looked at her.
"I was young once and I wanted things I could not get. "She said.Silence. "Now you sit down while I fix us something to eat."
She heated some beans and ham，made the cocoa，and set the table.The woman did not ask the boy anything.Instead，as they ate，she told him about her job in a hotel.Then she cut him a half of her ten- cent cake." Eat some more，son，"she said.
When they finished eating，she got up and said， "Now，here，take this ten dollars and buy yourself new shoes.And next time，behave yourself，son，from now on."
She led him down the hall to the front door and opened it. "Goodnight!Behave yourself，boy!" she said.The boy wanted to say something else other than"Thank you，Madam" to her，but he couldn't.In fact，he barely managed to say"Thank you"before he shut the door.And he never saw her again.
