This is a great greeting and departure for a large group who will be attending a seminar for more than one day together and the chances of meeting everyone in the room is almost impossible. Form two large circles (or simply form two lines side by side), one inside the other and have the people in the inside circle face the people in the outside circle. Ask the circles to take one step in the opposite directions, allowing them to meet each new person as the circle continues to move very slowly. If lines are formed, they simply keep the line moving very slowly, as they introduce themselves.
