Why do people need drama in their lives?

Ok looking for objective, PERSONAL answers, i have the psychological view. I am caught in the middle of drama which has nothing to do with me, but is between a good friend and my family. Both sides have valid arguments, but both sides are not without fault. Basically friend went and told people personal stuff about my family who in turn found out. the personal stuff got spread so in return the family retaliated and confronted the people involved. the whole thing blew up but it couldve been prevented HAD PEOPLE NOT BEEN DRAMA SEEKING! So now, I am looking for reasonable rational answers from normal people and not psychology textbook explanations. BY THE WAY: I have no choice but to be involved. i get it in the ear from both sides DAILY! and i have said not interested but then im being an for not caring and listening
