Doubles, not singles

Because two play at that game,

and playing alone would make me so lonely.

But I do.

Because this candlelit table seats more than just me,

and I'm looking at my watch, waiting for you, when they told me I should leave.

But I didn't.

And 

Because the tragedy lies in front of me,

and not behind, I should look both ways before I cross.

But I dare not.

Because you walked in,

and then quickly out.

But I did not stop you.

I am playing a losing game;

a game meant for doubles,

representing myself and only myself.

A player of singles,

enjoying a game of doubles.
