When I know something, I should be able to explain it, clearly, to a set of people who know nothing about the topic. If I can do so, without talking down to them, yes, I know that topic well.
One gets to see things in the most unexpected places. I went to see a 11-day-old baby, and I found this…Prashanth pointed it out to me in a plant that was in a flower-pot!
Why am I subjected to a daily barrage of forwards?
