The story of Martin Worries

That is a story which I've had to invent to my English homework. The main requirement was that the story had to begin with the phase written in bold::

As soon as he got out of the car, Martin felt uneasy. He was a good man, hard worker and he used to wear colourful clothes. That morning was quiet. He was a good employee, so he was in the office parking 20 minutes before time to start to work. He felt worried. Something important had to be the reason. He decide to remember what had done before go to work. He woke up, he had breakfast, he drove, no more. It was all right, but he felt each time more worried. He began to get nervous. What was the reason? Martin was able to guess the weather for tomorrow, he was meteorologist, but he can't know why he was worried. It began to be something important. He began to sweat. He needed to know why! Suddenly, he remembered something, he got it, he knew the problem: HE FORGOT TO SWITCH OFF THE BATHROOM LIGHTS!!!
