There are signal events that divide and change our lives. If you live in the south like I do, there is “Before Katrina” and “After Katrina.” We all remember what we were doing and where we were when Katrina made landfall. Millions of lives were irrevocably changed and many were lost. My mother and I were chatting earlier today and spoke about how the attack on Pearl Harbor in 1941 was another such event. My nation was forever transformed on that day.
