In this game, which I learned from Sakiko Ishitsubo, people pair up and take turns closely observing each other, describing what they see. When person A says, "I see you are holding the zipper pull on your jacket." Person B repeats the description, "I am holding the zipper pull on my jacket." In this way each observation is stated and verified. There is no strict sequence, players can shift back and forth as they like. The goal is to observe each other closely, to describe what you see, and to verify the observations.
For developing communication skills, noticing how we communicate.
