The body of the email is one of the following: • 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. • Click to attachment to load a movie 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 • Execute attachment to load a movie 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.
