Recently I took a walk inside the old city of Ahmedabad. Passing through narrow lanes and "Pols" of old city one feature I took particular notice was of windows of the houses which lined these lanes.
Social life of residents of these lanes,poles revolve around happenings in lanes,poles or squares they live in. Window is their viewfinder to this life. It is their link to the world outside their homes. Any new entrant to the area brings them to their window . People passing through are observed keenly,discussed and of course welcomed with open warmth.
Interaction with milkman, hawkers also sometimes happen through windows.
