It does make me wonder, though, if every such thing is doomed to become stale. Of course, arrangements (and Arrangements) aren't necessarily just about tabs in slots, etc.
Not that my own "arrangement" with my employer isn't as fragile (or more, perhaps) and susceptible to termination. I'm certainly vulnerable to being replaced by someone younger and cheaper.
There's a basic truth here ... nah, I'll just go look at some more porno.
