Do You Remember ?

 A woman awakes during the night to find that her husband was not in their bed.  She puts on her dressing gown and goes downstairs to look for him.  She finds him sitting at the kitchen table with a hot cup of coffee in front of him. He appears to be in deep thought, just staring at the wall.  She watches as he wipes a tear from his eye and takes a sip of his coffee.  'What's the matter, dear?' she whispers as she steps into the room, 'Why are you down here at this time of night?'
