Imagine, for a moment, an individual with a special all-consuming interest. They are interested in a particular, specific event. This event is aired on TV regularly. When that happens, our individual becomes an impermeable wall of interest. All attempts to gain their attention are wasted, as the only responses garnered are harsh shushes and brief, vehement protests. Conversation is an impossibility, and even during commercial breaks, it must be kept on the topic of the program if there is to be any hope of reciprocity.
