would like to ask you this question. I have been accused without any valid reason by someone in my class. this person keep insulting me on the group chats over the internet, and no matter how I explain, he is "so sure" about what I have done wrongly against him. however I didnt do anything and he has no valid evidence to support his proposition.
Could you let me know for a case like that, is there any ways that I can protect myself from being insulted, and to warn the person not to accuse me anymore coz it much affects my personal life.
