During those 36 hour train journeys between Kolkata and Bangalore, I used to have a small stopover at Chennai. I would dump my bag in the cloak room and wander around aimlessly in the streets. Soaked with perspiration under the hot sun, I would listen to snippets of conversation in a language alien. For those couple of hours.. all alone.. I was free from the past that Kolkata wrapped me in, free from the future that Bangalore offered.
