Difficult people can be a challenge to deal with in various aspects of life because of their negative behaviors and attitudes. They can create stress, frustration, and conflict in relationships, whether it be in personal, professional, or social settings. These individuals may exhibit traits such as aggression, stubbornness, selfishness, manipulation, or negativity, which can make it challenging to communicate effectively and resolve issues peacefully. One reason why difficult people are common is that everyone is unique and has different personalities, backgrounds, and experiences. Not everyone is going to get along or see eye-to-eye on every issue, which can lead to disagreements and conflicts.
