Imagine you’re on a camping trip with a group of friends. One friend (played by your partner) pulls a bottle of liquor out of a backpack and starts to pass it. Your entire group of friends drinks from the bottle before passing it to you. Begin your dialogue with your friend by assertively refusing the drink. You may explain your refusal in any way that makes the most sense to you. Your friend should then respond by trying to persuade you. Continue this role-playing until each of you has had a few opportunities to speak.
