Thank you. It's good to be back in the winner square. Thanks for keeping this punathon going.

I am reminded of my young days on the farm. This was before I went to university and got my doctorate in Mathematics. Back then, I stood at the edge of the pasture as two cows walked side by side. Just then, a second pair of cows joined them, and they all continued on in a row.

I was dumbfounded. I had never seen two and two be 4.
