Thanks for the thoughtful responses.

I am not familiar with the Openness to Experience OE, but I will look into it.

I also didn't have anything like tantrums or meltdowns in mind, but rather how to bridge the gap in understanding and empathy when one person in a relationship can hear the flowers sing and the other knows for certain that "singing flowers" is nonsense. "Owning" the difference still leaves one person crazy, alone or both.
