I don’t know if there’s an ideal number of people for a conversation, debate or any other form of interpersonal communication. For me the deciding factor in a perfect conversation is the subject matter. Only a very short time ago I was involved in an exceptionally interesting conversation with my sister and three friends of hers, that involved topics ranging from literature to history. We ended up referring to people like Jane Austen, and presidential assassins Booth, Guiteau, Czolgosz and Oswald. That’s the kind of conversation that can really keep my undivided attention, whether it’s only in a small group, or in a classroom with more than three dozen people. Perhaps it wouldn’t be a very good idea to have an overwhelmingly large group because it would be too difficult to keep track of all that’s going on and to give everyone present a fair chance to participate. As long as all present are interested in the topic or topics of conversation, the number can vary. Of course I quite often enjoy a good interior monologue too. The cast of characters who populate my imagination can keep me company especially well.
