10th and 11th Days of Christmas

This morning I received my gift for the 10th and 11th days of Christmas. For the 10th day of Christmas I got a little desk gift which contained a notebook, address book, pencil, and picture frame. For the 11th day I got a calendar for next month. I am back to square one of knowing who is doing this for me. I thought it was Heidi, but she claims its not her... Do I believe her or not?
