If someone challenges my self-esteem or insults me, then I will try to find out why it happened. I want to know first whether I have a mistake against him that I do not know. If there is my fault with him, then I will try to apologize.
If I have no fault with him, then I meet him to ask him why he is doing things that challenge my self-esteem, I will try to remind him not to do that again.
If after that he is still doing it, then I will report him to law enforcers, eg village leaders, police or justice. If this is not a response from them, I will reply in a way alone, the term eye eyed. The strategy can vary, which is important to make him kapok.
