The next suitable person you’re in light conversation with, you stop suddenly in the middle of the conversation and look at the person closely and say, “What’s wrong?” You say it in a concerned way. He’ll say, “What do you mean?” You say, “Something’s wrong. I can tell. What is it?” And he’ll look stunned and say, “How did you know?” He doesn’t realize something’s always wrong, with everybody.
The Pale King, David Foster Wallace
