Thank you for remembering me at Christmas with such a special gift. I'm really enjoying the <gift> you gave me. It was so nice of you to think of me during the busy holiday season and to take the time to search for and find the perfect present. I don't remember writing a letter to Santa, but you managed to find exactly what I wanted anyway! I couldn't be happier with it and wanted you to know how much I appreciate the <gift>. Thanks again!
