A few months back, I was trying to assist a family member in learning a new skill. Very early on things went wrong and there was a minor accident. No one got hurt but some economic damage was inflicted.
The young-ish family member gets the bulk of the blame for this damage. However, given I was the instructor and supervisor, I have to hold my hand up and say quite simply that I got things wrong, and moreover it is correct to blame me for getting these things wrong. And the passage of ten years will not make my contribution to this incident any less wrong.
The McCanns cannot keep Madeleine's disappearance high in the public profile and simultaneously expect the issue of their childcare arrangements to vanish.
Will you expect to be reminded that you got things wrong every day for the next 10 years?
In my experience there are two types of reaction when things go wrong.
1. People who are only interested in who is to blame, and want to concentrate on that.
2. People who say - 'What's done is done' and look for ways of putting it right.
IMO people who don't want to drop the blame game, do it because it makes themselves feel 'superior' to the person(s) who made the mistake.
Other people don't have that problem.
