Owning up to mistakes has gone the way of the dodo bird

Is it just me or does it seem as if 94.3% of people never take responsibility anymore, and in most cases, they then point the finger at someone else when confronted about a slip-up of theirs? In politics, in sports, at work, at school, between couples, between friends, between family members, seemingly anywhere and everywhere, when someone is called out on a mistake they made, instead of admitting to the error, they then point the finger at someone else. Why does it seem so difficult anymore to admit a mistake, attempt to learn from it, and not make that same mistake again? I'm not exactly sure, but this seeming shifting-of-blame epidemic does get aggravating at times. Here's an exaggerated version of what I'm talking about...

Setting: At the Humee residence in Washington, D.C.

Diana Humee: "Why didn't you do the dishes this morning before leaving for work?"

Donald Humee: "You never asked me to. Besides, you almost always do them."

Diana: "I left you a note."

Donald: "I never saw it."

Diana: "How did you not see it? I taped it to your wallet on the table over there."

Donald: "Maybe the fan blew it off."

Diana: "The fan wasn't on."

Donald: "Maybe the dog ate it."

Diana: "We don't have a dog."

Donald: "Do we have a cat?"

Diana: "No!"

Donald: "A son or a daughter?"

Diana: "No again! Just admit it! You saw the note and didn't feel like doing the dishes!"

Donald: "I don't know what you're talking about. Just admit you forgot to do them last night, remembered after I left for work that you meant to leave me a note, so you left a note after I went to work to make it look like you left it before I went."

Diana: "You're crazy!"

Donald: "Not as crazy as you!"

Diana: "Just admit you screwed up!"

Donald: "Not until you do first!"

Diana: "That doesn't make any sense, but I didn't!"

Donald: "Neither did I!"

Diana: "This is just like you! You never thank me for any of the notes I leave for you - even the ones where I say that I love you!"

Donald: "You do?"

Diana: "Ugh!"

Donald: "I mean, you leave me notes?"

Diana: "Yes!!!"

Donald: "Hey, what's that little piece of paper sticking out of your pocket?"

Diana: "What are you talking about?"

Donald: "Right here..." :: pulls out the note and reads it :: "Ah-ha! It says, 'Please do the dishes before going to work today.' So, you never did leave it for me, did you? Now who looks like the idiot?"

Diana: "How did that get in there? I swear to God, I left it on your wallet. You must have put it in my pocket somehow!"

Donald: "Without you noticing?"

Diana: "Yeah!"

Donald: "Whatever!"

Diana: "As if!"

...and they lived happily ever after. The End.
