He was just sorta shooting the breeze, and I couldn't hear him very well, which has to do with (1) I was largely asleep, (2) he kinda mumbles, and (3) working in clubs doesn't promote good hearing.
He said he'd call back later.
We did get as far as indicating that I no longer have a house, and am living in an apartment, so it wasn't a sales call. I suspect it has to do with the divorce lien fiasco.
Guess I'll find out later.

On the other hand, something fell out when I took the cover off. I think it was just one of the mounting screws, though who knows...
