Each person stands against a wall in the room, facing each other
One person moves towards the other, trying to guess how fast the person can move and how far the person can move
The other person does not move, tries to pay attention to his or her feelings and raises his or her hand when he or she feels that the other person is too close. The person moving forward stops until the hand is lowered again
At the end of the exercise, the pair debrief and then reverse the roles
