Highlighting the fact that we all see things differently depending on our own specific perspectives, a good activity that will help you make the point is to write a large number “6” on a letter size paper and put it on the floor. Ask half the participants to gather around and stand in front of the paper so they can see the 6 clearly printed. Ask the other half of the group to gather around and stand opposite the first group and behind the paper on the floor so that they can see it a “9”
Ask each group to say exactly what they see from their own perspective and highlight the point how we all see things differently from our own positions/perspectives.
