Final answer:
When conflicts with a roommate arise, initially engage in open communication to address the issues. If this doesn't help, involve a mediator and, as a last resort, consider changing your living situation.
Step-by-step explanation:
If you don't get along with your roommate, the first course of action should be to communicate openly about the issues you're experiencing. Approach your roommate in a non-confrontational way and try to discuss your concerns and feelings honestly. It could be helpful to come prepared with specific examples of behavior that is causing conflict. If open dialogue does not resolve the issues, consider involving a mediator, such as a resident advisor or counseling services, for support. As a last resort, you might look into changing roommates or living arrangements if the conflict is severe and cannot be resolved.
