But in my fancy, the owner [of the cafe]… must surely be a man, perhaps the woman’s husband or someone she lived with. Perhaps consumed with jealousy he had shut himself off behind the wall. Imagining the eyes of the customers creeping over his wife’s body, he was surely agonizing behind the wall. Perhaps there was a peephole somewhere in the wall through which he secretly observed the customers. Otherwise, there was no need for her to be perched like a bed, her legs exaggeratedly crossed, on the high, round stool which had been installed in front of the counter… She was worth being jealous of. Even I, who had no relationship with her at all, could only be jealous – in spite of myself.
Of course, if I could remove the wall, things would be resolved at once. … Without the wall the girl’s performance would at once appear rather artificial, and depending on the man’s attitude, quite comical. Of course, the price would be high. Her worth would be reduced by half at least. On consideration, her being worth jealousy was a part of her value, and it would be a severe loss. Regardless of who was responsible for the performance on the stool the man would never give up his own place. He is compensated in his own way by locking jealousy behind the wall with its agonizing thoughts.
