In the evening, we went out for dinner and I was asked to practice not wearing glasses some more. I didn't have my lenses in at this stage, but I can actually see without corrected vision - just not as well.
As it happens, the company was very enjoyable and the conversations were more of the mind, than they were of the "look at that thing over there" nature. It's one of the first times I've come away from dinner with a book list. I shall do my research. It's nice to be interested in something.
