I was riding in a car with two other fellows whom I had recently met. I had been doing quite a bit of trading in the stock market recently, and I was thinking about the prices of some stocks I was trading. The stocks weren't for companies, but for operas, which could be invested in like companies. When one fellow in the car asked me if I knew the names of any operas, I was surprised by the coincidence of his question. I was just about to say "Carmen," when the fellow blurted out, "The answer I usually get ..."and then he went on to hum a few bars from the opera Carmen. He was trying to make fun of people who only knew the opera Carmen. As he then good-naturedly began rattling off the names of other operas, I tried to recall the names of operas. I concentrated, remembering that the action of one opera took place in southern France. Was the opera called "The Marseilles"? I couldn't remember for sure.
