Ralph ran off a contractor I was in the process of hiring this afternoon. It was almost funny, or will seem so in a week or two once I calm down.

Picture the scene: The sun beating down in 90 degree heat outside the house; my pen poised to sign the paperwork for repairs, Ralph appearing, fresh from his nap and barefoot; the contractor clutching his clipboard. Ralph asks Why can we just clean the system? The contractor explains. Ralph asks the same question again. And again. Why can’t we just clean the system? Each time a bit more belligerently.

The contractor tries to explain what he has already explained—that the system is past cleaning—and then tries again. He draws Ralph a diagram to show what he means. I can tell that the contractor doesn’t understand why Ralph is sticking so doggedly to an idea he has just explained won’t work and I can see and hear Ralph’s growing frustration. Both men become increasingly defensive. Meanwhile I stand there feeling helpless to diffuse the situation.

The irony is that the contractor was recommending exactly what Ralph had told me he thought needed to be done just yesterday.

Ultimately the contractor said he didn’t think he could do the job and Ralph said something less than gracious back (I have blocked what). As Ralph headed back into the house, I apologized under my breath to the contractor, explaining briefly that Ralph has Early Alzheimer’s.

Was that a betrayal to ease my embarrassment or an explanation that needed to be given? Should I even use the A word since Ralph actually officially still as MCI but no one knows what that is? I’m not sure.

The thing is that in his glory days, Ralph was not an easy man to work for—a demanding perfectionist who was also careful about every penny—and I sometimes had to run interference, a role I hated then. Evidently I still do, but Ralph was coming from a different place this afternoon. Locked into a narrow loop of one question he wanted answered over and over, Ralph was not processing the information he was receiving.

Although he is rarely aggressive in dealing with me or anyone else now, different versions of this problem have come up several times recently, usually related to business matters. I generally try to avoid involving him, but sometimes that isn’t possible. Sometimes the people Ralph is dealing with know he has a cognitive problem and give him leeway; sometimes they don’t and become puzzled if not belligerent.

A few minutes ago I received a call from the contractor’s wife apologizing profusely, saying that the contractor had no idea and would be glad to help us in any way. Meanwhile, I have already called someone else to by tomorrow. My guess is that a lot of conversation with Ralph for the next week or so will focus on this afternoon. What did the guy say? What did you say to him? Have you found someone to fix the filter? Who was the guy who came to fix the filter? Is the filter fixed? I will listen and nod, straining to be patient and silently kicking myself for not handling things better in the first place.
