I was having lunch at the Senior Common Room with a couple of colleagues from different departments. Another colleague who occasionally dines with us came along with a blind woman and her Golden Retriever. They sat down and the dog curled up under the table. I introduced myself to the woman. “I have seen you with Keith Bright,” I added, referring to a colleague from my department, whose research concerns so-called non-handicapping environments, and who sometimes comes to the Senior Common Room in the company of blind people. “I do not know him,” she smiled politely. To my embarrassment, I must have recognized the Golden Retriever, a common species of seeing-eye dog in this part of the world.
