The definitive work on hiding in a box is of course the James Thurber story A Box to Hide In
, which you can hear Keith Olbermann (of all people) read here
. It's possible that this story is the most perfect example of Thurber's particular brand of neurotic humor. "There was nothing for it but to face life out. I didn't feel strong and I had this overpowering desire to hide in a box for a long time. What do you mean, you want to hide in this box, one grocer asked me. It's a form of escape, I told him. Hiding in a box, it circumscribes your worries and the range of your anguish. You don't see people, either."
