Dear Dr. Y,
As you know all too well by now, Mr. X is one dumb bunny. Need I say more?
I can’t refuse: He has no friends, or even acquaintances. Even people using adjacent machines at the laudromat have no awareness of him. He is intrinsically immune to the public stall “wide stance” maneuver. All who claim to know him are liars, and are of two classes: those who enjoy momentary selective scotoma, and those who instinctively shun him. Nothing further will be heard from any other living beings, since none who might falsely profess to have perceived him are likely even to possess the power of speech.
Yes, lunch, definitely.
