+INTRO: Two students sort out whose things are whose. Notice the switch: A holds something up and asks "What's this?" — it's near A, so B answers "That's your pen" (near you, not me). "This" and "that" flip depending on who is speaking. Just listen and read along — no repeating this time.
 INSTRUCTION: Listen and read the questions and answers.
