It is this special trait of living beings which sets them apart as a class having emotions, personality, behavior, etiquettes etc. Whenever something conflicting strikes the emotional behavior of the individual, the overall personality gets affected.
Once the personality disorder starts appearing in the individual and no cognizance is taken of the change in behavior, it gradually takes the shape of long term patterns, if there's no Personality disorders take the shape of long-term patterns, thus causing serious problems in relations at home and at work. Under normal circumstances, we as human beings often come across many stressful situations which results in tension like situations.
