As a child of God we are called to be people of integrity and excellence. We cannot just say random things that we think someone else wants to hear. There has to be a difference between you and the rest of the world. They should be able to know who you are by the way you carry yourself and how you handle situations. Remember to let your "No" mean NO and let your "Yes" mean Yes. By the way you do not have to give anyone a reason for your "No".... that is, once you become an adult.
