There is little to gain from carrying out a post-mortem on a situation, wondering if you should have done this or that, but try telling that to George Costanza.
George Costanza. From Seinfeld
‘Postmortem is when your mind rehashes or ruminates about what you think happened (or should have happened) in a social situation. Your “postmortem” review of a situation can last from seconds to hours, often “rearing its ugly head” from time to time long after you have left a situation. The following is an example of a “postmortem” review:
‘Oh no, I really screwed up that presentation. I should have prepared more. I can’t believe I made that stupid comment about finances. And I forgot to mention the plan I’ve been preparing. What an idiot! The boss sure had a disappointed look on her face. I bet she regrets promoting me. I’m going to get fired, and I’ll never get another job!’
