Always live in peace with everyone, with enemies - in neutral peace. You must to be in agreement with everyone - not with anger, but with polite words - it's important. You must say everything and repeat it politely, not with anger. Always stay calm, think calmly. If there is a disagreement, first say it again politely - only then explain each other, warning before - that you will conflict if not otherwise. It's best to postpone the question to think about it, changing the subject, knowing both positions. Everything should be said seeking agreement, not anger. In meaning seek agreement with the person rather than win of the conflict.
