During one week this month, the drivers of four taxis that I took hailed from four different countries.

One of them said his was a small country near India when I asked him where he was from, my standard question when I see the driver's nameplate. Nepal? No. Bhutan? No. Sri Lanka? No. The answer: Bangladesh.

I had never thought of Bangladesh as a small country, even though my niece Haruko had visited it as a foreign-aid officer after her three-year stint in Kathmandu. So when I came home I checked: Bangladesh is certainly not much larger than Nepal.
