My Roommates Set a Trap in Dialect, But I Understood Every Word

The first day of freshman year, right after I walked into the dorm, one of my roommates said something to me in the local dialect. I didn't catch it, and asked without thinking, "What did you say?" The three roommates exchanged a look and smiled. "See, I told you she's out of town. It's in her file. Riverton." "A hick from some third-rate city gets to share a dorm with us? What rotten luck!" "Isn't that exactly what makes it fun? She can't understand a word. We can insult her and tell her we're praising her, and she'll still have to thank us."
