Today would have been our day.
It would have belonged to us.
I would have taken you out, or made you a card, or done something stupid and cute for you.
But not anymore.
Now, today is just another day.
It is just another cycle.
It is just another routine.
Here, gone, back, tomorrow, gone again.
It is just one more interval of time consisting of me merely going through the motions.
Today is unremarkable, although it once was.
Today is a day, and nothing more.
