Dormitory Life
①Living in a dormitory at college can be a great experience. However, if you take no steps to make this experience positive, dormitory life can become a misery. When you choose to live in a college dormitory, you will have a better chance to live a colorful and meaningful life. Meanwhile, you will have to give up many things as well.
②When you live in a dormitory, you can meet many people with different interests. And you can enjoy the various services there. Both are very important to make you successful at college. But you may have to give up much of your personal space. You will share a room with someone else. This means you need to make peace with the things and people around you.
③You will have to learn some important life skills. For example, you will learn how to get along with people. You will also learn to ignore things that you can’t change. But in the future, you will find these skills very helpful when you are working in the world.
④When you live in a dormitory, you can enjoy a wide range of campus services, which are not available to those who live off campus. If you have any school related problems, you have no difficulty finding someone to help, because the school hires people to help the students living there.
⑤Besides, living on campus means you don’t have to travel to and from school in rush hours. And you are more involved in campus life.
