Bug.

I'd dream of sleep,
Sleep and wine,
If only life,
Would give me the time.
All those years,
You toss it aside,
For moments of fun,
On a passing tide.
Now here I am,
Day dreaming of sleep.
The overwhelming exhaustion,
When you fear you will weep,
At any little thing,
Not going your way.
When it just feels so hard,
To get through the day.
Then she comes smiling,
Wanting a hug,
And you remember this is transient,
It's only a bug.
