Sorry to seem generalistic, alcyone, but I wasn't really referring to your reaction, rather the fact that you reacted to the same line that Ann did. That's the only reason I mentioned you. I thought that giving my take on it might help to explain that line better for both of you. If I'm even close to what Terry intended with the line.
