when tidal waves hit, there are often people watching on shore. They see the disaster coming, see the horizon disappearing. They don't really see until it's too late.  while it's good to plan for the worst, you can't really know how you'll handle it until you're smack dab in the middle of it, under the wave, trying not to drown. Disaster has a tendency to melt away everything else in life.  So if you want to know who you'll be in a disaster, ask yourself, "Who am I now?"
