Timothy is a student at my school. He is well liked by all of the teachers and students. We all know that we can count on Timothy to keep our secrets, to help us if we ask, and to always be on time. We know that he is always honest and expects others to be honest as well.

Last summer, Timothy got a job walking dogs each morning. When school started this year, everyone encouraged him to quit his job, but he decided to keep it. He knew it would be hard to get up every morning at 5 a. m. in order to get all of the dogs walked and then go to school all day. Additionally, he planned to sing in the chorus, play basketball, and be a mentor in the tutoring program this year. He knows it will not be easy, but he thinks his hard work will be worth it. He is trying to save enough money to go to a youth camp next summer.
