Why were we in the dark?

The question is not, “Why did Josiah give his presentation in the dark?” The question is, “What happened when we were sitting in the (almost) dark?” What was it like to sit in the dark and listen to a presentation, or to ask and answer questions in the dark? What did it feel like, and where did those feelings come from? By “feelings”, I hope to evoke all possible meanings, so, physical and emotional feelings as well as thoughts, attitudes, or associations. How was it different from Laura’s part of the class, and why? What happened in the dark, and what didn’t happen? It was the first time in this class that we have been in the space together without being able to see each other clearly. Why is that not common?
