3 days, no keys

I recently lost my keys for the longest stretch yet. I have things in place to prevent this--friends have extra keys, there is a "landing area" by the back door. The problem was I went to Chicago with a friend last Wednesday, and she drove. That meant I entered and exited from the front door (for explanation see Alley Etiquette). Hense, the keys disappeared for the first time in a long time.

They reappeared today. Apparently our sofa bed eats things. This has happened before, and I thought it was a fluke, but the sofa bed really hides things. They don't just fall down behind the cushions, they work their way all they way inside the folded mattress.

Thanks to Zog, for the visual depiction of a sofa bed with an agenda.
