Forget about it; It's not important.

It really is not that important. You would worry about such things another time, but for now, forget. You are tired. You close the book. The thought runs through your head, 'who gave this to you.' It is not important. You put the book on the shelf, and head home. It is not important. You sleep well, and forget the book ever came to you. It is not important.

It really is not that important. . . what is?
