1. Sensitive and suspicious: People who hold grudges are often very sensitive to things and people's words and actions around them, easily capturing negative information in others' unintentional words or actions, and interpreting them excessively, leading to distrust and hostility.
2. Difficult to let go: They find it difficult to forget past hurt or dissatisfaction, and even if a long time has passed, they will repeatedly recall and mention it, making it difficult to let go. This personality makes them easily immersed in negative emotions, which affects their mental health.
3. Strong retaliatory mentality: People who hold grudges often have a strong desire for revenge in their hearts. Once they feel offended or hurt, they will seek opportunities to retaliate or seek revenge, even if such behavior may cause greater harm to themselves or others. They tend to use resentment and revenge to maintain their self-esteem and rights.
