Pepito wasn’t a very bright kid. He often failed his tests and annoyed his teachers. One day, his teacher, Ms.Emily, told him he had one last chance to do well. Pepito took a test, but inevitable failed. Ms.Emily expelled him from school and told him he was the dumbest kid she had ever met. She made sure he knew he would never amount to anything in life.

Years later, Ms.Emily came down with a very strange sickness, to which there was no known cure. Her only hope was a genius doctor who lived in Brazil, who had been developing an experimental treatment.

Ms.Emily flew to Brazil and asked the doctor for help. The doctor told her she seemed oddly familiar. When Ms.Emily mentioned she was a teacher, the doctor said he did very poorly in school, often failing tests.

The doctor treated Ms.Emily, and everything went well. She was weak and on life support, but survived.

But Suddenly, Ms.Emily turned blue and died. The doctor didn’t understand, everything had gone well. What happened is that Pepito, the dumb kid, worked at the hospital as a janitor. He had disconnected her life support just to clean a spot of the room.
