Calling someone while on the streets of a busy city can be difficult. You need to find where you can stand, get good reception, and most of all, be able to hear the other party. I watched as this woman retreated to a quiet corner of an otherwise busy street. She is probably traveling somewhere – a wheeled piece of luggage stands next to her as she cradles her phone in her hand before making a call. The image is an incongruous one -- here, just a bit before noon on a street corner of one of the largest cities in the world, someone finds a place to make a quiet call.
