Well, the movers never showed up. They were, however, nice enough to tell me that they would not be able to make it today when I called them at 12:00. It's roughly the equivalent of waiting for the cable guy, but at least they do, eventually, show up.
Instead, they will be here tomorrow.
This gives them only Friday and Monday to box up the whole house, and then 1 day to load it all on the truck. It's doable, but the experience I've had with movers is that when they rush, things break. Hopefully they won't notice the 500o pounds of beach sand I am shipping to Hawaii labeled "medical supplies."
