Law does not compel you to say ‘sorry’ and ‘thank you’. Law cannot be made to govern our behavior towards others. That is why, law is silent so far as manners and courtesy are concerned. Now the questions arise, “What should be our behavior towards others?” “How can we decide what is right and what is wrong?:” in this context a general principle is that one should not behave in such a manner towards others which one doesn’t expect from others. A gesture of others which annoys me should not be showed by me towards others. This should be the guiding principle of interpersonal relationship. Unfortunately, the same cannot be followed in reality. The problem arises when someone violates that principle. What should be the reaction of the person who receives such unexpected action? The root of the reaction of the person who receives such unexpected action? The root of the problem lies elsewhere. This is mainly because of the different temperaments of different persons and different perceptions about ethical norms.
