People who can’t do better are not “Mindful” they are not ‘Here Now’. They live in some nebulous fantasy.
They can’t prioritise, they easily miss the facts.
It can be amusing when they make their choices and exhibit their horrible behaviour to the exact wrong person.
What you need to do when in proximity to such a person is never say anything, suggest anything and practice social distancing.
They are failures in every sense.
If they are born to wealth they squander it. If they are not, they are always broke yet pretend they are rich.
They are such poor readers of character that they don’t know when someone takes them for the clown they are or foolishly, respects them. At least until they reveal themselves.
