Introductions

At the movies the other night, I had an interesting experience with introductions. I was there with two friends and one of them saw a very close friend and approached. Schooled in proper manners my friend, of course, introduced us to his friend. And his friend, taking the hint, introduced his two friends to mine. But what was abundantly clear was that we were not going to be introduced to my friend's friend's friends. There were three degrees of separation that were not going to be overcome, and nobody asked any questions.
