John Lennon has a lot to answer for. I prefer the Frank Sinatra description...
"Imagination is crazy, your whole perspective gets hazy"
Can you also imagine a situation where Lady H was mortified at the insensitivity she showed or might have willingly participated in some prior discussion of the attitudes that a host needed to show to everyone irrespective of their backgrounds?
Yes I can imagine that too...
I didn't imply she wasn't mortified after the fact, she's certainly said she was, I'm happy to accept her at her word. .
But I have also read that even palace insiders found her a tad 'imperious' in her manner, so that could suggest she might have been resistant if any suggestion of 'retraining'.had been made.
I could probably recount many many different imaginary scenarios, but that could get a tad dull after a while.
In contrast to Frank's appraisal I'd say that imagination is actually a very valuable thing.
One of its many benefits is being able to imagine how other people, who are not you, could feel in certain circumstances.
This can help in the development of empathy 👍🏼
