I think we were very possibly separated at birth garlic. INstead I got the wrong twin, the totally headfuck twin; toxic, a viper who never ceases to astound me 
so that's one down (toxic twin), many more to go in my immediate family. Scorpions would about sum them up. Can I possibly say I'm the only sane one among them? I don't feel I can, though this dawning, and shakey, realisation marks many years of self-examination/therapy, believing at the core for too long their version of events: that it is me who is mad. But I'm going off topic.
So, yes, she did hit a soft spot - the woman who got 'a piece of my mind'. I didn't get the 'ping' of anger that I know to act on immediately by getting AWAY (I once turned heel out of one boss's office because of the 'ping' in my guts that meant anything could happen and it was time to go. I came back when I'd calmed down after a walk around the block). What happened in the recent (controlled-ish) meltdown was an overflowing frustration and outrage, that cascaded out, like a flood, all 'training' nowhere to be seen
What I am saddest about is that the accuracy of my perceptions (and yours too by the sound of it garlic) could be used for tremendous good but are deadly when used to harm. I sometimes wonder if I am aspergers/autistic as my comments can, as you say garlic, deeply offend people's sensibilities; with me left in confusion re 'what did I say?'. People have sometimes reacted violently and I am none the wiser about what caused the offence - particularly as I'm supposed to know, it's supposed to be obvious and I am apparently being obtuse to not get it (at all, actually). One woman actually exploded "It's the things you say!!", which was hardly enlightening. I suppose I hold greater store in concepts (if that makes sense) than people's feelings, including my own; I don't ignore my own, or theirs, but expect us to be adult about our feelings. It may be an excuse - I don't know - but the insanity, the endless tantrums/strops/offences in my immediate family were just nonsense mindbending and impossible to decipher or negotiate with any degree of success, which left me clinging to rationale as the only bright spot in bedlam, the only thing that made any sense. Perhaps those of us who hail from chaotic, narcissistic families are only comfortable with The Facts.
I would also never allowed to speak in my family. it was absolutely forbidden for me to speak. I am still not allowed to speak but I don't associate with them unless I have to, having reached a safe truce which satisfies our parents (we are all 'speaking' - ha! not all of us!!) but gives me the freedom to choose the level of contact and at which I do my best approximation of a block of wood.
