Mary Jones, programmer, is dating Joe Smith, a sysadmin at the NSA.
On the side, Mary is secretly seeing entrepreneur Paul Morris, and is keeping a diary of her feelings in Fargo . Of course she doesn't want Joe to see the diary, but she's heard that he can access any documents stored on the Internet. So she turns on encryption for her diary, and therefore is reasonably certain that Joe's prying eyes will not be able to read her innermost thoughts.
Confident in her privacy, she dumps both of them, and moves to Venezuela.
