I saw and enjoyed Samuel Beckett’s “Waiting for Godot”.
15 or 20 years later I read the play.
When I came to the character of Lucky, I was curious why the play had omitted that extraordinarily unlucky character.
As I read the play the other characters on the stage reemerged in my memory, except for Lucky, and his master.
In the following days the stage image of Lucky emerged from my memory.
I had edited out that character from my more accessible memory.
With effort and time it was accessible.
I suppose Freud would have called this phenomenon “repression of painful memories”.
I recall only having been appalled at Lucky’s situation, and that might have sufficed to put some sort of block on the memory.
The memory was, however, vivid when it did emerge.
