Living in this world, there are many problems that we need to resolve. One of these problems might be caused by different opinions in two person or a group which would lead to a quarrel. Different opinion does not mean that we do not understand each other. Moreover, it is normal because everyone has rights to think by oneself. I, too, once had a different opinion with my friend. Different opinion is not the problem anymore as long as we know how to manage it. If we cannot change the other's opinions, why won't we change ours or find a better way instead.
