the rivalry exists because you all told me it exists

Is this akin to "I think, therefore I am"? Anyhow, who needs a reason? Is "just for the fun of it" a good enough reason?

we have an assistant principal from Wales, but I thought he was from Australia when I first heard him speak. Does this strike you as being strange at all, hev?

Not particularly strange, WW, although I have also worked with a Welshman, and there's no way I'd have mistaken him for an Aussie. Maverick may be the person with the most opinion (and/or knowledge) about this matter...
