An earring disappeared inside our home, and shortly afterwards, the whole house was vacuumed. I spread out a set of newspapers and emptied the vacuum bag over them. Then I went carefully through the ash, sifting – unsuccessfully – for that earring.
I've hardly ever done that before, but examining vacuum cleaner detritus struck me as a most natural activity. My father did it every the time the vacuum was emptied, when I and my brother were young, because we were little devils about putting small things in inappropriate places. I don't know what he found, but it sure was enough to keep him looking.
