Let's speak about ways and means how humans observe their environments.Divide into two groups, group 1 forms the internal circle, group 2 forms the external one. Two people stand against each other, face to face. After posing and answering a question like: How do You observe ? By what sense do You prefer to observe ? What do You observe ? members of G1 move to the left and members of G2 move to the right. Gradually, all members of Group 1 are supposed to speak with each member of Group 2, and vice versa.
