Four AM can be a devastating hour. The day, no matter what kind of day it was, is indisputably over; almost instantaneously, a new day begins: and how will one bear it? Probably no better than one bore the day that is ending, possibly not as well. Moreover, a day is coming which one will not recall, that last day of one's life, and on that day one will oneself become as irrecoverable as all the days that have passed.
