Tom liked to play at school. He had not been doing well in the exam.So the angry teacher decided to ask his father to come to school to have a talk with him.When his father came,the teacher said to him,"Your son didn't work hard,and even worse,he cheated in the exam.
"How do you learn it?"Tom's father said,"Since Tom has the same answer as the girl's.The girl sits next to him."Then the father said,"Then maybe the girl copied my son's paper."
"Oh,no!There are ten questions on the paper.Your son's answer to the first nine questions are just the same as the girl's.To the last question the girl answered,'I don't know.'And your son wrote:"Neither do I.'"
