My Favorite Story - What makes a good story?

The stories we've read in our humanities class were "Lamb to the Slaughter" and "The Sniper." My favorite one is "Lamb to the Slaughter" because the author builds a lot of serious tension that leads us to the climax. I liked how Roald Dahl made the story more interesting by making Patrick a police. Another thing I like about the story is the exposition Roald Dahl introduced his characters with a little mystery by making Patrick act unusual, and finally we figured out Patrick wanted a divorce. The thing that every story must have is a conflict in "Lamb to the Slaughter" the conflict is Mary v.s. Patrick. The conflict is important because it makes the story have a meaning full ending the resolution.
