Sorry to get metaphysical, but in the last few weeks, I've lost my new hat, my bike pump, and my classic iPod . . . and it makes sense that my iPod disappeared into the same wormhole as the other items, because -- as everyone knows -- mysterious events happen in threes . . . BUT . . . when my wife went into the shed to get some gardening gloves, she found the bike pump -- exactly where I was looking for it (and I really looked) so the pump wasn't missing at all . . . which makes me feel like Dr. P. in Oliver Sacks classic book of case studies, The Man Who Mistook His Wife For a Hat, and maybe my wife will find my hat and my iPod, but I don't think so, so then there has to be a third thing missing, and I think that missing something was once located in my brain.
