She's home!!! Still on TPN; it's an open question whether she'll be off it in time to enjoy a bit of Christmas dinner, though things seem hopeful; the radiologist seemed to think it was looking good on Friday. But she's home, in her own comfy chair, and I don't have to worry about taking her back in four hours.
I went over to fetch her at about 9:30; she got out at about 10:45 after we went over her meds and signed the last of her paperwork. Most of that time was spent ferrying stuff out to my car; my little Honda Civic was pretty well packed.
The house feels right again, and I'm a contented Bear.
