Question Of The Evening

Why is it when celebrities break up, it always mentions that the two are still "good friends" and "being mature about it" and if there are kids involved, "keeping them a priority." Sometimes I just wish the truth would come out - "we hate each other's guts, I have wasted x years of my life together, I hope you get herpes from the whore you cheated on me on!" That would be so much more refreshing.
