Write down the names of about five very different people on the board (a small baby, a rude waiter in a restaurant, a fashion model, a stranger in a crowd, and a grandfather). Give students a common expression, such as "Good morning!" or "Sorry!", and ask students how they might say it differently when talking to a different person.
