The other half of me

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.
And 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,
Could make me complete.
Is there a chart for the heart, or a graph?
Will we meet on the street with a laugh?
Will we know one another,
If i ever meet my other half?
The other half of me.
