I remember the problem of things falling off the bed very well. I was noticing just the other day that I seem to have very quick reflexes for catching things that threaten to roll or fall off somewhere near me. With all this work on the blog, I'm beginning to wonder if I might have developed these at Thorpe Arch. As you say, if something fell off your bed there, unless you could get a walking patient to pick it up for you it might as well have fallen into a bottomless pit, lost for ever. In the end I just got a bit lackadaisical about losing things, which used to drive my mother mad when I got home!
It comes up, too, in Margaret Vicars's posting (8th July) about her efforts to pick things up for other children, once she could walk - even though she couldn't walk very well!
