Kafka on Alienation

I wrote (link):

I remember reading somewhere—Walker Percy?—that Kafka’s first readers (listeners?) in Prague used to collapse in helpless hilarity.

Yep, here it is: it's part of Percy's argument that "there is no such thing, strictly speaking, as a literature of alienation:"

The reading [person] rejoices in the speakability of his alienation and in the new triple alliance of himself, the alienated character, and the author. His mood is affirmatory and glad. Yes! that is how it is!--which is an aesthetic reversal of alienation. It is related that when Kafka read his work aloud to his friends, they would all roar with laughter until tears came to their eyes. [Emphasis added-ed.] ... To picture a truly alienated man, picture a Kafka to whom it had never occurred to write a word."

--Reynolds Price, "The Man on the Train,"
in The Message Found in the Bottle 83 (1975)

Now, if I could find the one about Chekhov...
