My wife is the same, Otis. Sister or brother seem to be more or less the same as cousin. My wife's mother is from Azerbaijan, and the number of cousins, aunts and uncles that my wife has is bewildering.
I don't see that mentioning the court case is 'blurring the lines', Nick. That said, I certainly don't expect that bloody Seppala woman to reply, but I would be surprised if Wasps didn't (even if it was a standard non-commital response).
