triggers

PWD tend to "loop", to run through the same set of questions and comments repetitively. One advice is to eliminate "triggers", whatever it is that causes the PWD to enter the loop. I've been doing that already to some extent by discarding letters, etc., for which DW wants an explanation. But there's one trigger that's hard to eliminate.

Our DD (dear dog) has some hair loss on her back. The vet does not have an explanation and, therefore, a therapy. DD is almost always in our presence, and definitely when we walk her, so the trigger is always there. And the loop goes something like:

DW: I'm really concerned about DD's hair loss. Has she seen anyone? (DW sometimes uses the term "dog doctor".)
Me: Yes, I took her to Dr. C recently, and he said he didn't know what was wrong or what to do about it.
DW: Will it grow back?
Me: I hope so, but I don't know.

You can imagine that this loop gets old on a 1/2 hour walk.
