But did the ring fit? And if so, how did Ian know what size to get? Did he borrow a ring from Adam's dressing table, like Oliver did from Caroline's?
And how come Caroline's fingers are all the same size? My fingers are all different sizes. If someone borrowed one of my rings at random, chances are it would fit ONE of my fingers, but almost certainly not my ring finger as, at the moment, I am neither married nor engaged. I am puzzled.
