Finally this evening, as I was doing some desultory tidying, I was gathering up and combining various trash receptacles, and just to be certain I didn't throw this stuff out by accident, I gloved up and went through it all by hand. It wasn't that bad - the one thing about not cooking too much is it makes for fairly inoffensive trash. Lo and behold - success! I found everything that was missing, except for the letter opener. That, Xiombarg has probably carried off and hidden in one of her secret toy caches. But I can cope - I was the most concerned about the dvd, since it wasn't mine.
Turned out my appointment of the other day at UWMC was scheduled for 8:00 a.m., so I made the right decision to haul myself out there at the crack of dawn. I was even there on time, all unknowing. I love it when a plan comes together.
