... if person Y, who didn't read person X's mind, removed the feeling of victimization from the response, the behavior of expecting person Y to read person X's mind would diminish?......

...even if person Y went ahead and watered the plants anyway? Wouldn't the response of watering the plants - with or without the feeling of victimization - reinforce the expectation for person Y to read person X's mind?

If person Y felt that watering the plants was important, even though person X was being unreasonable in the way he or she brought it to Y's attention, then watering the plants might be a good thing to do. If person Y avoided doing something he or she felt was important just because of the behavior of person X, person Y would still be allowing his or her behavior to be dictated by person X. So the healthiest thing person Y could do would be to do whatever he or she thought was the best thing to do with regard to watering the plants, but to do it because he or she felt it was a good thing to do (or not do), and without feeling victimized by person X's behavior.

Boring, dry, dull, technical stuff. But if someone could come up with a therapy or whatever that would be applicable across many situations in which any number of dynamics might be working at any time, then.........???

Then they would be Dr. Phil.
