Making enemies isn't random. Traits like emotional instability, aggression, and disruptive behavior early in life can lead to antagonistic relationships. Research on students aged 9-14 found that negative behaviors, such as lack of empathy, increase the likelihood of mutual antagonisms, a pattern seen across genders and school levels. Emotionally struggling students were 35% more likely to develop enemies, showing that how we manage emotions and interact with others early on can have lasting social and emotional effects.
