Courtesy is the consideration for other people and is one of the outcomes of being good mannered. Courtesy helps us to gain more friends because a well mannered person is always liked by others. It even has the capability to reduce the number of enemies and gives an entirely new opinion even if you are at fault. Courtesy is not only the character of the high profile people; in fact it is a must.
Even great enmity can be thrashed in a minute by a simple act of courtesy. “Gratitude is the most exquisite form of courtesy” said Jacques Maritain. Courtesy has the tendency to be reciprocated and is also infectious. It will be returned with the same quantum that you offer. To quote Confucius, “When music and courtesy are better understood and appreciated, there will be no war.” So, develop this trait of being courteous to make the world a beautiful garden.
