Blame is often shifted. Responsibility is avoided.
Responsibility for anything and everything is passed along like a hot potato. That is, when the outcome was negative. It's quite the opposite if things turn out favorably. But, if it doesn't turn out well, or if something was forgotten, or if something wasn't done right, suddenly no one stands up to admit their involvement.
We want to seem blameless. We don't want to be held accountable.
Pies that turn out bad. Well, the fruit wasn't ripe. Progress that is slow. There aren't enough people helping. Books that are lost. Someone else must have moved it. Food that isn't ready. She didn't get the food out of the freezer in time for it to be cooked. The appointment that was forgotten. He didn't remind me. The anniversary that was forgotten. Well, it's been awfully busy around here. And on it goes.
Sure, there are many factors. And maybe you aren't solely responsible, but if you had any involvement, stop hiding behind others and things you can't control. Be accountable. Be dependable. Be responsible and take responsibility.
Stand up in honesty and take responsibility for the things you did have control over.
