Shalom Auslander tells the story of the time he went on vacation, pegged the guest in the room next door as an impostor and devoted his holiday to trying to prove it. Shalom Auslander is the author, most recently, of the novel Hope: A Tragedy.
There's a famous William Carlos Williams poem called "This is Just to Say." It's about, among other things, causing a loved one inconvenience and offering a non-apologizing apology. It's only three lines long, you've probably read it...the one about eating the plums in the icebox.
