I drove to Pune today. It was a hurried day trip; driving back in the evening, I am a couple of kilometres away from my home. A car is crawling on the Western Express Highway beside mine. It has the same last four digits on its license plate as mine. It is registered in Pune, where I just came from. My car goes ahead a few metres, then his overtakes me for a few. We do this a couple of times over the next kilometre.
After a while, the driver of that car has rolled down the window and asks me for directions to a location that is nearly the place where I stay.
Does coincidence have another name?
