I was thinking about how very often members of a group form a natural order. I know wolves do it, and I'm sure other creatures do too. Perhaps we could formulate a list for this forum?
I suppose you'd have to start at the top with Roger, and work down. (Probably having me as second).
Or you could start at the bottom, with Mince, and work up. Is there some kind of order of importance already psychologically established, I wonder?
