I cannot write a love poem
Only one of love that's lost
Is it because I have no love
And my heart must bear the cost
Or could it be, that words flow well
When the heart is aching so
And it's easier to write words
When love decides to go
Love is such a strong thing
Many people have said before
It's amazing what the heart can do
When you lose the one you adore.
