I picked it up. I put it down again. I have a memory of putting it down at just about waist-height, with my right hand. This was in the house.
We have looked everywhere at just about-waist height. We have looked in the places where things might get knocked, or fall, from somewhere of the right height. We have looked in all the usual places. We have looked in some unusual places.
We have not yet found the camera. Blog posts are going to be a little uneventful for now!
