Light the World - day eighteen

Each year my sweet little Elf brings a little treat and leaves it on my car seat in the early morning hours beginning the 12 days before Christmas.  It is usually some candy, useful Christmas plates or glasses, decorations, candles, wrapping paper and bows, or some other item to delight and please me. He has done this for years and I appreciate his thoughtfulness and kindness to me. He is my true love and he takes good care of me.  I wonder who it could be?
