Yes, I think that a lot of people continually blame themselves a long time after the mistake has been made. I suppose it depends on the ramifications of the events. I certainly see and blame myself for the mistake, but try to learn from it.
It is when I repeatedly make the same mistake that I get annoyed with myself - it's like " didn't you learn the first 5 times??'
