What should my roommate do if he stays up late and doesn't turn off the lights every night?

What do other roommates think? This kind of person's character is useless. ) I have met before, and the most effective way is to give up what you have and tell him together that if you don't change, you will be kicked out. I told you, your face has been given!

Besides, my roommate thinks it's ok, so I personally think it's still influential. Just tell this roommate (usually this kind of person won't change) and move yourself if you don't change!

Pure personal handwriting, my personality is relatively straight, which is what I did before, and it is the first way!

If you can't adapt to the environment and can't change the environment, then change the environment.
