One morning Harry came to his mother while she was having her breakfast, and said to her:"No one at my school likes me,Mother.The teacher don't and the children don't.Even the cleaners and the bus drivers ."

"well, Harry, perhaps you aren't very nice to them.If  a few people don't like a person,he or she may not be responsible for that,but if a lot of people don't,there's usually something wrong, and that person really needs to change." Her mother answered.

"I'm to old to change.I don't want to go to school." Harry said

"Do't be silly,Harry.You have to go.you're quite well and you still have a lot of things to learn.and beside that,you're the headmaster of the school.'
