Old Lady Neighborhood Watch
Throughout Europe, old ladies (and men, I suppose) spend a lot of time at their windows, looking down at the activity on the street below. From their perches, they function as a sort of informal alarm system, ready to witness any mischief and call the police. A Portuguese art collective known as CC went around the Lisbon parish of Anjos and put signs under their windows that parody the logo of the Securitas security firm.
Vigilant old ladies: another good example of the value of neighborhood social capital (and urban living).
