Harry came to his mother one morning and said to her that no one at his school liked him. The teacher's din't, and the children din't. Even the cleaners and the bus drivers hated him.
His mother answered that it was such sad news and she added perhaps he wasn't very nice to them because if a few people din't like a person it might not be his fault; but if a lot of people din't, there was usually something wrong with such a person and he really needed to change.
Harry said that was good advice and he added that he was too old to change. and he didn't want to go to school.
His mother said not to be so silly,she added that he had to go because he had things to learn and besides that, he was the headmaster of the school.
