Arguments affect people differently. After a disagreement with a partner, friend, family member, or coworker, one person may cry, replay the conversation for hours, or struggle to sleep. Another may appear calm, return to daily life, and show little outward sign of distress.
From the outside, this difference is often misunderstood. People who don't visibly break down after a fight are sometimes labeled as cold, emotionally detached, or uncaring. Others assume they never feel hurt. Psychology paints a more balanced picture.
