Kavin (while arranging the cash in my wallet after using it): It is impossible to align all the Gandhi faces. They face in different directions.

Nilay: Is Gandhi the only good guy in our country?

Kavin (vigorously): No. He was racist.

Nilay: They should put a reflective surface on each note and write "You. You are the good person of this country."

I was marveling over the brilliance of this thought, so I tuned out of the rest of the discussion. It was about the practicality of putting a reflective surface on each note. Mirrors were ruled out as they would break, the edges would hurt people, and they also wouldn't fold. Kavin, ever the engineer, observed that pasting any kind of reflective surface on a production line where millions of notes are produced daily, would lead to a deluge of challenges.
