It's the day that everybody in the world remembers
because they can 't forget it:
The eighth day of the week;
the thirty-second day of the month;
the thirteenth month of the year;
The day that's not on the calendar,
Yet never off it in your mind;
The loneliest day of your life
which everyone shares;
The most unreal day
Yet most real;
The longest day
which hasn't ended yet;
The day whose hurt you want to forget
Yet want to remember in every detail
So that it can hurt more;
Yes, how can I forget -
it's the day you went away.
