Superego: Return your library’s ebook copy of The Dream Thieves straight away.
Id: No. I want it.
Superego: Yes, I know. But remember? You own it now! In hardback. You impulse-bought it at the store.
Id: Because I wanted it.
Superego: Yes, because you wanted it, and you didn’t run that purchase order by me before making it, but that’s all water under the bridge. Now you have it! Hooray! You have it in hardback. Return the library ebook copy so somebody else can read it.
Id: But I want it.
Superego: YOU WILL STILL HAVE IT.
Id: Might want it on the bus one time. On my Nook.
Superego: Then you can wait the twenty minutes until you get home! And then you can read the hardback copy you greedily purchased for yourself.
Id: BUT I WANT IT THOUGH.
