When you aren't drinking or using drugs or spending lots of money on fancy toys or basking in the glow of fame or working all the time or eating your way through the refrigerator, being hateful and angry is a very handy shield from the truth. It lets you focus on everyone else's shortcomings, and all the ways they have let you down. You can bemoan how all these broken people keep finding you somehow. That way you don't have to focus on what really matters -- the tough work of fiing what is broken inside you.
