Conflicts have always accompanied people's relationship, but it is hard to say whether disputes and misunderstandings can be avoided or not.
On the one hand, I do not see why peaceful cooperation of people may not last long. One of the ways is that each of us should show good will if we want friendly relations to endure forever or for a long time. Another way is that in case of misunderstanding or suspicion we should talk to each other and negotiate what can be done to continue on friendly terms. Yet another way towards peace is that we should follow the proverb "Do as you would be done by", which means that we should treat others as we want them to treat us.
On the other hand, good intentions are not always effective. Some people are quick to show their annoyance and vent their negative emotions on others. Another reason is competition among individuals or groups and the desire to have more than everybody else. Also, arrogance and domineering behaviour may also trigger off a conflict as nobody wants to be humiliated.
By looking at the two perspectives, I certainly believe that small conflicts can be avoided. Annoyance and anger can be treated calmly and patiently without adding fuel to the fire. Talking of competitive behaviour, we can deal with it by raising our own performance and increasing our own results. As for arrogance and dominance, it should be met firmly but tactfully setting a good example to the other party.
In other words, it is my position that small conflicts in human relations are avoidable and life without heated debates can be a reality.
