I am not responsible, somebody is cheating me therefore I am suffering. But why you desired that nobody should cheat me? And this is not in our hand we made such a world that no body should cheat me. What we should do? We can make up our mind that we should accept his cheating and we should keep in mind that is his doing so that he will suffer of his doing.
You will not be able to change the mind of others. If you don’t make complaint and don’t bring misery in your mind by his doings only then it is possible to change his mind.
