Secondly, it is a lot of work to choose your own roommate. For example, if I did want to choose my own roommate, I would first pick some candidates from the list supplied by the university. Then I would write to them and they would write back. Through our letters, we would find out if we shared common interests, such as sports or movies. Because of my investigation, I would probably get someone compatible with me. However, it takes time and labor to go through, though. Besides, the process of finding similar interests is not all that different from what the university does.
