 I walked a short distance toward my car. This is on the NIH campus. Suddenly and without warning, I broke into tears. It is a good thing that it was the middle of the night because I would have been terribly embarrassed if any of my colleagues had seen that. However, after about a minute and a half, I felt fine and the brief outburst reminded me that indeed I could still express genuine human emotions despite a job that required that I remain as cold as ice.
