Response to Simon's "Giuseppi's Secret"

Although I had read an earlier, shorter version of Simon's "Giuseppi's Secret," I didn't actually realize it was the same story until the last scene, when a giant comb is presented to the narrator. I found this interesting, because I already subconsiously knew the climax of the story, but still wasn't able to catch on to the hints of what Giuseppi's secret was. I really love subtlety in fiction, but when hints are so subtle the introduction of a giant greasy comb jumps out and startles you at the end, I would push to rewrite the story in a manner that would give the reader more foreshadowing to what Giuseppi's secret is.
I love Giuseppi's character. The response to Mister Thomas's question about what the hell is wrong with him with, "Misaaa Thomas, I am a very busy man. It is difficult for me to leave my house for I have a sick brother," gives a lot of insight to this Giuseppi character. Actually, when he said he couldn't leave the house for he had a sick brother, I immediately reached the conclusion that this guy is crazy. I'm not sure if that's the response Simon was hoping for, but I personally found it quite satisfying to read. It tipped the reader off to the fact that Giuseppi's not a normal human, but, honestly, I would prefer the abnormality to lie in something more dramatic than housing an enormous comb.
And, so what? So what if he does have a gigantic comb? What does that bring to the story? If it's a magical realism thing he's going for, I'd understand this plot twist a little more, but I still want more about the narrator's reaction to the comb, and the reasons for why Giuseppi adores and cares for it so. Is it an obsession? Was he cursed? Is it all in his mind? Why does he smile for the first time ever as soon as it's smashed before his eyes?
This story raises more questions than it answers. That being said, I am interested in having those questions answered, and think this could be made into a much stronger story if some of those questions were addressed. One other thing Simon could do to strengthen the story is to define the relationship between the narrator and Mr. Giuseppi more. By the end of the story, when they are in an intimate, personal setting, I was unconvinced Giuseppi would trust (or even know) the narrator well enough to show him his big, bad secret.
Overall, the story was engaging and pleasant to read, but I feel there are some plot holes and that the characters could be developed a little more. Simon clearly has an active imagination, but I would like to see that imagination answering more of the questions his story poses.
