I can never reveal my greatest fear

I can never reveal my greatest fear
The terror binds my tongue
I have come to terms with the inevitable
But i don't know how it'll change me
As sure as the earth turns
I'll wake up one day to find her gone
Not my flesh or blood,but a bond just as strong
and when the last goodbye comes
I hope she'll know how much she meant
And how she changed the world around me
how she is the reason for a million smiles
And that i've always thought of her with moist eyes
Wish we could live twice.
