While standing next to someone you know, try out a “conversation” with them. It could be about anything, but it must be important to you. It could be what you want for dinner, or maybe about the state of the planet. Once you two are happy with the general form of your conversation, stand at the mouths of each of the speakers and repeat your conversation!
With 4 people, have person 1 and 2 practice their favorite conversation. 1 and 2 then go to each of the speakers and say their thing. Have the 3rd and 4th people stand in the middle between the speakers, and try to debate their ideas. Change roles and repeat.
materials: paper and pens to jot down ideas.
