If you like absurd, existential, surreal, kafkaesque stories with loose ends or writing that explores the psychology of the modern individual inside the mess of social approval and shared experiences, then you are going to like this.

The Couch, as the photo in the cover, traps the sitter. Contemporary society has developed some standards of behavior that may push individual expression to a corner.
The unnamed protagonist/narrator himself goes blind when attempting to escape his usual boring routine and that makes him think about other 'smaller' problems that torture him.
And while the first part of the story presents an absurd situation, the second part reveals the absurd response to that situation: the protagonist doesn't even care about his blindness, to the contrary, this is the day where we actually see him experience his boring routine, as if nothing had happened.
But in the midst of his boring socializing and supressed personal-crisis, the protagonist routinely decides to reveal a 'big secret project' he has been developing for quite some time right at this very moment.
This rings as a desperate action towards personal expression: the protagonist didn't succeed on doing something on his own the previous day, but how about expressing himself onto the people he can't get away from or trying to affect the structures he finds himself in?
The answer is not positive. After 'his disatrous showoff', as he puts it, the protagonist decides to blend in and leave his own impulses behind.
Good or bad. That's what happens.
