Use the listener’s name: “Hello, Marta,” shows it’s not Marta speaking, so it’s gotta be the other person in the room. Speaker can do something: “Hello, Peter.” She flipped her towel and spread it on the sand. Speaker can take an action toward the listener: “I thought you’d want these.” Peter handed Marta the snapshots. Use the location: She rolled over in the sand. “What did you ask?”
