Conflict is inevitable in life. Each one of us has his/her own views that are not necessary same to others views. While you think something is good, others might think is bad. likewise, you might think something is unacceptable while others think is acceptable.
Neither avoidance of the conflict nor high emotions will be able to resolve the conflict. You must use reason to resolve the conflict. Reason is rational, logical and professional way to resolve conflict.
