This is how I hide me from myself:

I am holding a thing
An idea comes to me
My brain shifts its occupation to that idea.

### HAND
> Do we need Thing for Idea?
### BRAIN [preoccupied]
> What? No. Put it down.
### HAND
> Got it! Where does it go?
### EYES
> Brain's busy, but that spot looks good.
### HAND
> Ok!

And so Brain carries on, unaware of what has happened to my wallet or keys or whatever.
