Okay. I guess it's not fair for me to interject too greatly in this, but there may be other reasons why there may be shortages in one region, why people may not want to move, and so on. That's not reflected in these figures. In any event, it is curious.
If you want to add more to that as you go along, fine. I don't mean to take too much time away from others.
Mrs. Hughes, you're next, I guess.
