It's the morning after Christmas (and I don't let Christmas go that easily). It's called Boxing Day. So in the clean up and discarding of torn wrapping and cardboard boxes, you find one gift that had gone unopened. There's a note:
"Sorry this one got lost in the numbers. In my haste, it had inadvertently gone undelivered. You became the last stop for the year. If this caused you any embarrassment or inconvenience, I'll make up for it next year. Merry Christmas!
What was the gift? Was it expected? Or was it a total surprise? There is Christmas magic that lasts the whole year. This is a bit of it. Your Flash Fiction concerns this last gift of Christmas!
