I can't shoulder all the blame

Just last night I got into a little trouble when I told everyone that my big sister can not hold her liquor. Well it was not all bad in the beginning. Actually a great number of the ninjas around me agreed that she needs to see someone...that it was or is crucial. Only problem came in when much later in the night, one bugger comes in and thinks it is "tell all" night. Mr. McCan't Shut Up goes on to call my sister to tell her how much fan we are having and starts saying things he shouldn't have. Now partly it is my fault, good friends do not let one make drunken calls. I'm sure it is in the Bible somewhere. So my sister is furious and all. She calls me spitting fire and then my Darwinian senses just struck like a juggernaut into a wall. I instinctively threw my drunk fool of a friend under the bus like it was second nature to me. I completely turned things around on him making him the villain just so I would face my sister without having one of those weird moments where it is just the two of you and you can't even look at each other. Come to think of it, it is second nature to me...I have done this before, and I always have. And the sooner others evolve to that level the better they cam maneuver in their little lives.
