I can totally relate to this. I am not entirely sure that everyone does pick up on the hidden voice/meaning you are referring to. When you have a nack for it you just think every one does it, but I don't think now that this is the case. You can just tune in to the person that little bit deeper, no matter what their words are expressing, there is something more to it. Yes in obvious cases like with your son you knew what he was alluding to as you had made a promise. But in more general terms, interacting with people in general, knowing when someone is bull shitting you etc is like some form of intuition.
I think i struggle sometimes because all my life i just mostly know what someone really means no matter what they are articulating. And would be confused by what seemed like mind games, in some cases it was blatantly that, but most people have different motives for beating around the bush per say. I decided in my early twenties that I would just try and be straight with people, if it concerned them, so if someone upset me say my b.f i would just tell him as it is, not have a go, maybe not at the time if he was worked up and not receptive. But some time soon after i would mention it. I've always been very clear with people to just be straight with me because you hiding it will hurt more than what you have to say. I almost feel disrespected.
This is a great way to filter out the narcissists in your life! They hate the straight up-ness and inability to manipulate you. But at the same time anyone can miss interpret you, my b.f will feel like I am having a go at him sometimes and without blowing my own trumpet, sometimes dam right i am having a go! But other times he is totally projecting, it can make people very uneasy when you call them out. Its surprising that people say they want truth etc but are unsettled by it at the same time. Kids are great, the toddlers, they just say whatever they are feeling or thinking and there are no repercussions. You know exactly what they want or dont want, when they are happy or sad or tired, they don't manipulate or hide things. We learn that we should!
I'm glad you understand me. Disrespect is such a good word - although it sounds a like out of a mafia movie :)
It's great if you've managed to teach people around you to cut the bullshit. I haven't managed that, so the best I can do to protect myself is setting up a defense perimeter.
Teaching! & Upsetting some! But, it was either that or my sanity! I think it's necessary to have some defenses, most often this 'intuition' works off the back of intense emotional capacity, and they do need protecting. But as i mentioned you'd be surprised how not normal this is. Millions of people identify as such but mostly you'll be the only one in your family/social group and so you can't build a wall around everyone ! You need to let some people in and be honest with them and clear about feeling disrespected :) one or two took it the wrong way and still do if i just put something across straight, it has strengthened relationships too. Just some advice, Good Luck xxx
