Late delivery

Less than 24 hours after the last traces of Christmas have been cleared away, our post lady brings... a Christmas card. It takes the form of a family portrait, and inside is a key which identifies and names each family member. The family owns the business I work for and, perhaps surprisingly, these cards are valued and appreciated by both colleagues and customers. People even collect and save the cards, noting the progress of the family as it grows older and larger.
And maybe it's not really all that late - last year's card arrived in the third week of February.
