It was terribly dangerous to let your thoughts wander when you were in any public place or within range of a telescreen. The smallest thing could give you away. A nervous tic, an unconscious look of anxiety, a habit of muttering to yourself-anything that carried with it the suggestion of abnormality, of having something to hide. In any case, to wear an improper expression on your face ... was itself a punishable offense. There was even a word for it in Newspeak: facecrime.
George OrwellYou had to live - did live, from habit that became instinct - in the assumption that evey sound you made was overheard, and, except in darkness, every moment scrutinized.
