How to explain to my son that the warning signs were so slight? That disaster, when it is quite sure of its own strength, will announce itself by hardly moving its lips? They say that in the hour before an earthquake the clouds hang leaden in the sky, the wind slows to a hot breath, and the birds fall quiet in the trees of the town square. Yes, but these are the same portents that precede lunchtime, frankly. If we overreacted every time the wind eased up, we would forever be laying down under the dining-room table when we really should be laying the plates on top of it.
