I was working for a large corporation from home on 9/11 and part of my job after the attacks was to contact some 75 employees to verify their safety. Remarkably, several of them were scheduled to be in one of the Towers that day, but they had stopped for coffee & a preliminary meeting before going in to the customer's office.
I'll never forget the sound of the anguish in the voices of the families who hadn't heard from their loved ones yet, nor the happy tears when they were later discovered safe. What was most compelling was how everyone joined together to do whatever they could to help others.
What a wonderful world it would be if we could sustain that sense of fellowship and teamwork after the crisis is over and never forget all the people who were lost or irrevocably changed.
