One day Mark was riding his bike when it began to rain. He started to feel cold sohe looked for a tree to go under for shelter. He was disappointed when he struggled to find a tree. Someday I am going to inspire people to plant trees everywhere, so he thought.
Once he got home, he took out his social studies homework and went up to his room to do it. While he was going to his room, he saw his dad throwing away a piece of paper which was used only on one side. He was about to stop him but it was too late. Someday I am going to inspire people to use both sides of the paper, Mark thought.
When he woke up the next morning, Mark figured out a way to inspire people. He would put posters around the school. Then he took out eight sheets of poster paper. He made four saying "PLANT A TREE FOR ME," and another four saying "PAPERHAS TWO SIDES, SO USE BOTH."
He went to school early and put the posters around the school. After class, histeacher told him to go to the principal's office. Mark had never been to the principal's office before. What if the principal had to punish him about the posters because they never asked him to put them up?
When Mark walked in nervously and took a seat, Principal Marcus told him "I would like to thank you for inspiring people to help other living things. When I was on the way back from my lunch break, I saw seven fifth graders planting a tree and heard a few others telling someone else to use both sides of the paper and I'm pretty sure it's because of your posters." Mark couldn't believe his ears. He had finally inspired people. Mark felt very proud.
