A short smile, can win manythings. It can resist an undesireable matter also. Only, that you would need, to approach with your smiling face. Many tension or turmoils, that could be tackled smoothly ultimately.The degree of anger whatsoever might be high,that could be nutralised somehow after proper persuation. But,first of all, you have to smile to do all.In some cases,you would need to laugh louder,as to confute the matter of contention,without saying ‘No’ directly. Such practice could help you to bring your opponent, to be with you. Smile or laugh,both have equal impact on moulding anyone’s negative attitude, and that should be applied keenly.
