Saying those words can be difficult but they open the path to change. It doesn't have to be phrased like that unless you just hit a baseball into someone's front window. (You did stick around and make arrangements to cover the cost, right? ). You might have said something like, 'I could have done better,' or 'I think next time I'll try it this way," or even 'I'm going to start writing down my appointments so I don't forget them.' Any of these phrases, or something similar, all have something in common: You are taking ownership for your actions.
It's interesting how people like taking credit for something they did that turns out well, even if success was also a surprise to them. But admitting that what happened was a direct result of your actions is not so easy when the outcome is negative. Perhaps society, in the form of parents and teachers, must bear some responsibility. We could see errors, bad choices and poor behaviours as teachable moments, suggest ways to improve and then --this is the important part -- hold children accountable for improvement. But sometimes we choose to rain down criticism and punishments without future solutions that leave the child/student deciding to avoid future similar events at all costs. Thus, is blame someone else born.
Some children/adults will lie -- if they think they can get away with it. Even with the chocolate cupcake icing smeared on their face they will deny that they took one after being told not to before dinner. In a two year old it's almost comical. Some people get good at lying, straight-faced and with righteous indignation that someone else was to blame. The problem is there is this thing called credibility. The courts rely on it a lot to decipher the truth and most of us develop a sixth sense about it even though it is not reliable. But once you have categorized someone as a liar or at least prone to fantasy or wild exaggeration their future veracity is in doubt. Kind of like the boy who cried wolf.
I think there is an inherited component to it. Young children who never acknowledge that there are areas of their education they need to work on - like not habitually losing assignments before handing them in will often have parents, who at parent/teacher interviews, will tell me that relatives came to visit or that the child had to go shopping with them or that Johnny wasn't feeling well as the reason homework was undone. How many times do excuses work before they don't? Children grow into adults and hang onto their habits. It's always someone else's fault that they can't hold onto a job, get into a financial bind, smoke and abuse prescription drugs. I don't know if by now they believe their own excuses but I sometimes notice that they seem to check to see if the person they are talking to has bought into their excuse or do they need to work on honing their pitch.
