My family has no problem and we live a very happy life. My mother is from Hung My, my father is from Hung Nguyen. But there are poisonous relatives who are always looking at me, wanting me to go into danger. But, my parents had very good strategies to protect the family as well as me. Toxic people tend to be forced to get attention at all costs. Even if it's someone else's birthday, malicious people will always find a way to turn things around them.
If in this situation the best course of action is to pay little or no attention to the person, and instead spend more time with the quieter and more discreet people in the group. Prior to this, smart people will develop a solid network of support from loyal and trusted people.
They know they don't have to be friends with people, and that not everyone is worthy of their friendship. On the contrary, they give their friends loyalty and trustworthiness by showing them that it comes from both sides.
