This is a short Swedish Story I found on the internet. A story with a single and easy, but not less important punchline.
A little girl – with very demanding parents – had problem in school. The more the parents nagged, and tried to attract her attention with all imaginable kinds of rewards for her to do well, the more distanced she became from school. She was also “all over” in class and disturbed all her class mates.
But then one day, one month into the semester, she came home from school with a smile on her face. The next morning she went up early and did her homework and went straight to school, which became routine thereafter.
In the parents meeting, held during the semester, the parents knew that their daughter had made good progress, and that she was very talented. Now that she was motivated, everything went easy on her.
The principal explained that it was largely due to a special teacher who had started at the school which their daughter took particular liking to. The parents asked the daughter to show them to that amazing teacher to thank him. When they met him, they discovered to their surprise that he was dumb.
– How can this man be a teacher, exclaimed the father, he can not speak!
– But he can listen, replied the daughter.
