This story is now published as part of the anthology ‘Loyal and True’.
Carol and William had an unusual relationship.
It may have been unusual but it worked.
After university they traveled to Korea and it was there that they discovered a tradition that they would modify and take as their own.
In Korea a married couple would receive a pair of carved wooden ducks.
The ducks would be displayed in a prominent place in the married couple’s home.
When the man would come home from work he would discretely look at the ducks and if they were facing each other he would know that his wife was amenable to love making on that evening.
If they were facing away then she was not in the mood.
Carol and William employed the ‘vacancy’ sign; the meaning was obvious.
