What's the experience of having a terrible college roommate?

My roommate is a terrible person. He is neat and serious. Every public facility in the dormitory should be placed neatly, and lines must be drawn, and then things should be put in the lines and placed neatly.

Only in this way can he stay comfortably in the dormitory. If the things in the dormitory change, he will feel very uncomfortable, and then he will clean up the dormitory himself until it looks like what he wants. So that our lives have been greatly affected.

Besides, this roommate is too timid to turn off the lights and sleep. For some reason, he always turns on the light when he goes to bed every night. But it is difficult for us to sleep with the light on. But if one of us turns off the light and sleeps, he will lose his temper.

Another one has a roommate who is in the physical education department and is very strong. Whenever we make him angry in the dormitory, he will glare at him, so that we are afraid to contact him later.
