Now and again,
something comes in exactly when I need to hear it.
Not exactly the situation, but pretty darn close to applicable. And sums up my point of view rather well. Talking with Knuter the other day, I think the adjective was, "negotiable." These plans, as stated before, are all considered to be "Plan B". They're the backup in case nothing happens.
Completely unrelated, today's new word for me is "plotz". I am eagerly searching for a way to use it conversationally - unfortunately, a good chunk of my day is at work, and they expect me to behave myself there.
