at five o'clock in the morning, everything is still and the streets are empty. that's what one would expect: yet there is a life that goes on: crows cross the street with their resolute step, approach the cars chosen well in advance, call out to each other their morning news, sit on rooftops and adjust tv antennas to their favorite programs. unlike humans, crows are never in a rush. they pass from garden to garden unhurriedly, enter unfamiliar kitchens and enjoy quiet breakfasts at the table, peck through the morning paper, and scrupulously balance their accounts. at five o'clock in the morning, people are entirely unnecessary.
