oh I see

Lots of people regret their inability to respond immediately and resent the time they spend later tossing about in bed  fussing about what they should have said. It's frustrating, to be sure,  to come up with a good line several hours too late. I don't have that problem.  I never think of a riposte at the time when I need it or even later when I don't.  What I do have is incredibly acute hindsight, but it doesn't do me any good. It's not 20:20, not at all,and it's random.  It's microscopic, no, that would mean it's small and it's not, in fact,  It's often broad and encompassing and enlightening, and although it frequently gives me pleasure, it doesn't do me any good at all.  My best insights come to me as if through the wrong end  of a telescope,  so far removed from the events that caused them as to be useless. Years later I figure out why someone was annoyed with me (who, me?), or how someone misunderstood the facts of a case, or what I - they - really meant.  All the random thoughts that play in my head like Dodgem cars suddenly  bump into a new pattern.  An insight?  Yes. Oh, I see.  Oh, dear.
