“Pillow friends are not just good friends. Oh, they are that, too, but they also get hot and sweaty together and muss up the sheets something fierce. By the way, pillow friends is a term used in the White Tower. The same relationship between men or women elsewhere would be called something else, depending on the country.” -- Robert Jordan's Blog
