   • Click to attachment to load a picture
Love at the lips was touch
As sweet as I could bear;
And once that seemed too much;
I lived on air

That crossed me from sweet things,
The flow of - was it musk
From hidden grapevine springs
Down hill at dusk?

I had the swirl and ache
From sprays of honeysuckle
That when they re gathered shake
Dew on the knuckle.

I craved strong sweets, but those
Seemed strong when I was young;
The petal of the rose
It was that stung.

Now no joy but lacks salt
That is not dashed with pain
And weariness and fault;
I crave the stain

Of tears, the aftermark
Of almost too much love,
The sweet of bitter bark
And burning clove.

When stiff and sore and scarred
I take away my hand
From leaning on it hard
In grass and sand

The hurt is not enough:
I long for weight and strength
To feel the earth as rough
To all my length.

I woke up in a white room
with white lace curtains.
Snow covered landscape;
I’m in Memphis for certain

Yesterday, it took over three hours
just to travel the last twenty miles.
But nothing is like my wife’s family
always being greeted with smiles

I was hoping for a White Christmas.
You’d be surprise how simple I am.
Be careful what you wish for
God may be listening to your plan.

Most of the nation is covered
with that dangerous and beautiful thing
I am grateful for arriving safely
for my wife’s happiness is everything.

She wanted to see her family,
her father, uncles and aunts.
I ve kept her in Southwest Texas too long;
this trip I most willingly grant.

So, here we are now
in a snowy southern wonderland.
Waiting for Christmas dinner to come;
a present only my wife can understand

A stranger came to the door at eve,
And he spoke the bridegroom fair.
He bore a green-white stick in his hand,
And, for all burden, care.
He asked with the eyes more than the lips
For a shelter for the night,
And he turned and looked at the road afar
Without a window light.

The bridegroom came forth into the porch
With, "Let us look at the sky,
And question what of the night to be,
Stranger, you and I.
"The woodbine leaves littered the yard,
The woodbine berries were blue,
Autumn, yes, winter was in the wind;
"Stranger, I wish I knew."

Within, the bride in the dusk alone
Bent over the open fire,
Her face rose-red with the glowing coal
And the thought of the heart's desire.
The bridegroom looked at the weary road,
Yet saw but her within,
And wished her heart in a case of gold
And pinned with a silver pin.

The bridegroom thought it little to give
A dole of bread, a purse,
A heartfelt prayer for the poor of God,
Or for the rich a curse;
But whether or not a man was asked
To mar the love of two
by harboring woe in the bridal house,
The bridegroom wished he knew.
