One day, a man was enjoying a jog in the park. On his way home, he saw volunteers cleaning up the park. He thought to himself, I want to volunteer, too.The next weekend he volunteered at the park. It was hard work, but he was happy to clean up the park and contribute to the community.Later in the evening, he returned home to find many dirty dishes and laundry in his room. He was terribly tired from volunteering and could not do his chores.
