TUCUMAN, Argentina — Coming home to my native Tucuman, a city in the north of Argentina, has become almost a ritual for me. And, predictably, it has its bittersweet moments.

Tucuman and New York, where I have lived for the last 40 years, are quite different — the former relatively small and gregarious, the latter big and anonymous.

Bitter moments include learning of the loss of loved ones, whose impact is greater after living far away. The loss is compounded by a feeling of nostalgia. It happens when realizing that the city one has left is now a totally new city, a totally new and different urban landscape.
