A landmark event, one about which we will ask down the road, "Do you remember what you were doing when the news came?", or say, "I was talking with so-and-so in the drawing room when my friend ... called with the news."
Something so momentous that we remember the time, place, smells, colors, everything else about when we hear the news.
Unfortunately most news like that tend to be sad news.
But in this case I concur with my friend who said "The one pure happy news after 35 years." (Bangladesh was born in 1971.)
Congratulations, Dr. Yunus. And thank you very much. I hope you inspire many more.
