There are times when we have disagreements in business or personal life. It can be due to unmet expectations, communication gaps, ego, or anything else.
We are social beings. What differentiates us from other animals is our rational thinking. Disagreements need to be sorted out in a conversation, with both sides making a point of maintaining mutual respect.
Time and again we have seen our ego trumping over rationality affecting the overall greater good of both parties. All disagreements need to be handled with respect and in a cordial manner.
