I like to ask people about their childhood fears because I was a fearful child. At five, I avoided the TV room for a week after glimpsing something with a face like gobs of wet clay groping its way up a staircase. Only years and nightmares later did I learn this was Martin Landau’s entirely sympathetic mutant in the Outer Limits episode “The Man Who Was Never Born.” When I was nine, I was freaked out by faces more awful than Landau’s lumpy one.

Is it worse to be lonely in a crowded room or lonely in an empty one? Perhaps you have an immediate response to this, one you’ve pondered before now. It’s certainly not a new question, but the truth is that most of us have never had much of a chance to really know for sure. Even those who pride themselves on being introverted are often forced to spend a tremendous amount of time with other people. The average life, in fact, tends to be arranged around interaction.
