If someone accused me of a crime I didn’t commit, I would deal with this in three stages. First, I will propose finding a place which we could sit down together silently to communicate face to face. I hope the someone could tell me the real reason why accusing me of a crime I didn’t commit. If I can help him resolve the problem, I’ll try my best to give him hands, and then I will spend some time to talk with him about a moral issue as a man.
If he rejected my invitation from the first step, I will find our same friends or colleagues who can convince him. Let him realize the importance of this issue he accused me. This is my second step.
The final step, If I have given him two chances above, he still keep his thoughts and affect my reputation , I have to hire a lawyer to resolve this problem.
Luckily, there is no this kind of people around me.
