Giving all of anything is
Quite a commitment
Particularly when
There is no way
Of knowing what
Time will be required

All of me
All of my love
All of my time
All of my days

Whether part of a 
Cross-my-heart promise
Or the title of 
A favorite song
Life does not tell us
How many days remain

A definitive number
Is found only in
The days passed
Never to return

So, I settle on today
This hour, this moment
Right this second
That is all there is
And I must choose
To give all or nothing
