it must be Friday

Hat brushed, shoes shined, Windsor knot snug, mustache combed.
And she...she puts her hair up for the grand occasion: The anticipation and thrill of receiving a scribbled card from her Love miles and miles and miles away.
A knock on the screen door. The dog barks. He retracts 3 steps without turning his back, standing at respectable eye level.
'Ma'am,' nods the familiar friendly face.
'Oh!'
'What does he say this time?'
She turns the card over in both hands, eyes darting.
'He's coming home,' her voice breaks.
