All the facts in the story are telling and showing the mental problems that the main character has. The young man always says "I 'm not a mad man", but actually he is telling us that he is. The young man can't just kill the old man because of his old eyes. It misleads readers to have those horrible thoughts with the main character in the story. If the main character thinks that he is right, then he must have mental problems. If the narrator agrees with the "young man", then he also has some problem. And if someone thinks that it is a great story, then I suggest you go to see a psychologist. Is this product review negative?

input:  Now, answer this question: Title: Runs great but absolutely no parts or support! Review: Sharpener has run well for two years but needs a new set of cutters as they get dull over time. Being a "commercial" grade sharpener we bought several for the school. They have run well at all grade levels for over two years. I removed the cutters and called the Bostitch company to order some new cutters. Much to my surprise I was told that they do not sell replacement cutters for any of their sharpeners and that dull blades are part of normal wear and tear on the sharpeners. Their recommendation is to but new ones. That I will but they will be Elmers/Xacto models that have replaceable blades from now on. Shame on you Bostich for contributing to our landfills and not supporting you products. Consider this a lesson learned. For a home or small office fine but for a school/commercial application avoid this product. Is this product review negative?
