The wasuremono, the "forgotten thing." Whenever leaving a bus or a train, we are told to be careful of our forgotten things, the Japanese way of saying "Be careful not to forget anything." But how can I take care of my forgotten things if they are never forgotten? I've never really understood what a forgotten thing was.
And then the other day, a friend of mine tapped on my practice room door to present to me my cell phone which I had negligently left near the locker room. My wasuremono. For how long does it remain a wasuremono? Until the end of time? My forgetfulness has bequeathed this item with forgottenness. And now I can be careful of it in the future. Until something is forgotten, how do we know to care for it?
