Bluefang, Whoever said it was a done deal? Read my analogy. It speaks of a journey, not of a destination. It may be that contagious Bill gets on the bus sooner than we expected. In which case, it's exit the backdoor pronto. Or the bus crashes into the very sign we wish to avoid running into.
All I know is we're on the Barrett bus, the man in the big blue overalls is eating krispy kremes, and the little flower girl is on board but playing coy.
