How do you deal with people who, when in an argument, or a heated discussion, their go-to response is "I'm not a bad person!" or other such handy catchphrases as "try putting the shoe on the other foot" when that wouldn't even be relevant to most of what the argument is ever about and, last but not least "I try my best".
The same responses wheeled out no matter what the discussion is about this could range from cancelling plans and not updating the relevant people to kidnapping the next born child of the royal family, it wouldn't matter... no acceptance of their responsibility in any form, ever or willingness to see or understand how their actions affect others.
Inclusive of then flipping any heated discussion or argument to somehow be a semi shouty one about how hard they have it - tired, overworked, skint, trying so hard all the time, has blue mushrooms growing out of their arse, whatever...
How the fuck do you deal with it when you have to live with this person or can't 'not' engage with it??
