I was getting ready for work and listening to the radio. I thought it was a small plane lost in the fog, then I turned on the tv and saw the carnage. When I got to work, everyone had gathered around the television. I guess the silence was universal... I still get tears thinking about it.
That afternoon I made a bag of popcorn and accidentally opened it under one of the heat detectors, setting off the fire alarm. When the fire engines arrived, I almost cried. The crew leader said not to worry - it was a good distraction for them that day.
