Understanding your roommates and your neighbors will take some work. To help prevent conflict you should respect others' thoughts and ideas. The following are some tips for you to think about.
Lack of communication is usually the source of any conflict.
Don't expect your roommate to be your best friend and constant companion. Discuss potential areas of conflict. Be open to compromise. If your roommate is doing something you don't like, talk about it right away. Be considerate of your roommate's privacy.
