Classic Poem

Somewhere there has to be
The other half of me,
The other half of me
I've yet to meet.
One special someone whose heart has a similar leaning.
If she were right for me,
Day and night for me
Would have meaning.
The other half of me,
That unknown quantity,
That unseen destiny
Would make me complete.
Is there a chart for the heart, or a graph?
Will we meet on the street with a welcome laugh?
Will we know one another
If I ever meet my other half?
The other half of me.
