I felt so much sadness and for the dog, I could not believe that the guy just leaves the family dog in a neighborhood. Even though a dog may be annoying and destructive, it's still a part of your family. Abandoning a dog is like dropping off your kids in a bad neighborhood. When Al dropped the dog of, I actually felt like crying.
I was confused on why Carver named the story "Jerry and Molly and Sam", you only read about those three character's once. Sam is apparently some old neighbor, Jerry is the bartender, and Molly is someone that Al meets in the bar. They are the least mentioned characters in the story and don't really help with the development of the story. It is this type of title that makes me think.
I also felt anger against Al because he was a terrible person. This guy drinks (it doesn't specify if he drinks allot), he has affairs with other women other than his wife, and lies so much. I think that he deserves for the dog to not take his back. Also how dare he tell his wife everything will be fine, even though he is lying.
Overall though, I liked the story, it kept me interested.
