crossing the "invisible line"

I would like to say that I try to be funny when I give a hard time to the teacher but I actually like her little practices that she does. The thing that I like about the diversity practice we did last time was that everyone got to see how difficult it could be for those that are "differennt" but one of the things that I notice also was that any time anyone of us stand along across the invisible line, they all seem to have a certain sense of understanding for what the person across the line was feeling. I liked it. I think is important that other establishments where there is a group of people should try this kind of exercises.
