     The drug store was closing for the night.Young Alfred Higgins,the shop.assistant,was ready to go

home.Mr.Carr,the boss,stared at him and said:"Hold on,Alfred.Maybe you'd be good enough to take

the things out of your pockets and leave them here before you go."Alfred's face got red. After a little

hesitation,he took out what he had stolen.Mr.Can"said."Maybe I should call your mother and let her

know I'm going to have to put you in prison."

    Alfred thought his mother would come rushing in, eyes burning with anger.But,to his surpnse, she

arrived wearing a smile."Hello, I'm Alfred's mother.Is he in trouble?"she said.Mr. Carr was surprised ,

too.He had expected Alfred's mother to come in nervously,shaking with fear, asking with wet eyes for

a mercy for her son.But no, she was most calm, quiet and pleasant and was making Mr.Carr feel

guilty....Soon Mr.Carr was shaking his head in agreement with what she was saying.''Of course,''he

said,''I don't want to be cruel. You are right. Sometimes, a little good advice is the best thing for a boy

at certain times in his life and it often takes the youths long time to get sense into their heads."And he

warmly shook Mrs. Higgins's hand.

     Back home, without even looking at Alfred, she said, "You are a bad luck. It is one thing after

another,always has been. Why do you stand there so stupidly? Go to bed.''In his bedroom, Alfred

heard his mother in the kitchen.There was no shame in him,just pride in his mother's strength.He felt

he must tell her how great she was.As he got to the kitchen.he saw his mother drinking a cup of tea.

He was shocked by what he saw.His mother's face was a frightened,broken one.It was not the same

cool,bright face he saw earlier in the drug store.As she lifted the tea cup,her hand shook.And some

of the tea splashed on the table.Her lips moved nervously. She looked very old.He watched his

mother without making a sound.The picture of his mother made him want to cry.He felt his youth

coming to an end.He saw all the troubles he brought his mother in her shaking hand and the deep lines

of worry in her grey face.It seemed to him that this was the first time he had ever really seen his mother.
