You probably don't remember this, but several years back, you got a money order for about three hundred dollars. You tucked it between the pages of a book you were temporarily interested in. Then you lost interest in the book, and when you couldn't find the money order, you eventually figured out another way around it.
You left the book behind when you moved, and I think it's in storage now.
The money order is between pages 67 and 68, and is still good.
