Proverbs for Paranoiacs, cont'd: If you are travelling in the Second World, and a large commercial van with dark tinted windows that was outside the apartment yesterday pulls up again the next morning, and then pulls away again a few minutes after you put some towels out to dry in front of the window, it's undoubtedly a coincidence. If anyone's asking.
[Update, apparently just a van in the local commercial traffic that decided to make an abrupt departure at that particular moment. But in the Balkans, any excuse for paranoia is useful. Keeps one on one's toes.]
