in one of our classes, I teamed up with a group of people, and made a project Long Time No See that involved everybody in our class. We asked the whole class to stand in a line. Each student closed his or her eyes, put their right hand on the shoulder of the student who is in front of him or her, and followed the steps of the former student to bypasses some obstacles.
After the performance, the students seemed to really reflect on the message. We sympathize with people who are blind but honestly, being blind is much more difficult than not being able to see temporarily. By participating people got the ability to walk in the shoes of another and "see" the world the way the guide did. It was a new perspective for all those involved and we are glad that we could contribute such an experience.
