Oh, a thread about me. That's very interesting video, thanks for the heads up.
Verbal RapportApparently, I am not sure I am using this rapport stuff -- perhaps not face-to-face-style. Since I have extreme social anxiety, face-to-face conversation is impossible for me if there were more than one people nearby. So I guess I manage to build up my ways to make sure I do not speak wrongly over the years of using only text conversation.
Text RapportTo learn to have this rapport thing in text style, or just simply to avoid getting pretty much any trouble or possibly misunderstanding -- remain a calm stance in front of everyone within any text conversation is easy, one have to speak gently, lengthen the words, gather enough information to make them rather convincing, make them interesting, make them easy to read, never use fully capitalized words unless necessary, manage attitude towards the one conversing with, and most importantly, avoid any kind of possible confusion and elaborate every related points as much as possible, make sure the grammar is properly written, never rush, never use slangs or abbreviations that could anger someone due uncertainty that forces someone to look up unnecessary information through unnecessary steps, never type broken words such "hey u, comere boi", follow the speaker's common sense rather than oneself, and make sure the idea between the speaker and oneself is in sync.
All of these is just to avoid building up negativity between the speakers.
Inner and outer self personalityWhat's more important is that the way one speak one easily shape one's outer-self, but your inner-self is hidden away, and it is impossible to know exactly, because it changes randomly by many environmental factors. Due to that, it is best to not converse by using your inner-self, but rather, hide your darkness, and create a respected personality that does not have any particular negative aspect that could deemed potentially harmful, or this rapport thing.
However, shaping the outer-self also requires one to involve their own inner-self. With a bit of psychology thinking, it's easy to judge that the way I, myself, speak like this, just like you said, it feels like I am a sly person, doesn't it? Since I manage my stance strongly, it's quite easy to think that I am a villain behind my mask. Whilst your outer-self revealed that your inner-self speaks for you being too self righteous.
However, all of these can't be really considered true, yet neither false, it's unknown as there is no way to actually know that, what we're doing is just judging by its appearance. Of course, judging isn't a bad thing, it helps others to realize their mistakes that they're doing.
Inner-self and trustworthyIf one's outer-self is broken, it can easily harm one's stature regardless, and undoing that damage can take time, and possibly be impossible, there is no true way to know if one's stature damaged has been mended. Even if others say "You're forgiven", it's nothing more than words.
To actually proof that, one have to "act", it has to be shown verbally -- in any possible way. For example, well I am not arguing with you now, am I?
Even revealing one's outer-self, and/or inner-self to the others needs to be proven through verbally as well. Doing so will gain trust from the others, that oneself is not lying about oneself's real personality. It will only cause nothing more than trouble, if it's a lie, and definitely don't reveal inner-self that is commonly hated. Perhaps a slow approach, that may avoid sudden any sudden over-unconvincingness.
A good personality, and common senseBy common sense, human's instincts are always towards peace. What one needs to do, is to manage this peaceful personality of oneself, to avoid conflict, and resolves any situation through rational decisions. Well, unless anger decided to yank it away, that, can be bad.
Edit:
Just kiddingOh, as for the just kidding part, it is very important as well. Because when you make a joke in front of someone, there are people that are unable to differentiate between what is real, and what is not. Sarcasm and irony can be extremely harmful if it is not properly spoken, and confusion can occur as well. The confusion part can be countered by revealing that it is a joke by the end.
However, that doesn't mean that harmful jokes can be just ended by "Just kidding". Leaving an apology, is the utmost important endpoint.
Now, I said all these to piss you off.
Ha!
No, no, I was just kidding... Sorry.
Where did I learn?It is entirely experience that has been built-up over the years with only text-conversation. Edit 4: I'm sure many of us do or have experience of this.
Since I have social anxiety, and certain mentality illness, it is very important to ensure that any trouble has to be avoided.
Edit 3: Ah, wait, some of my points seems broken... Hmm... Never mind.
Edit 5: Too long, didn't read; I guess to sum up, just be positive? Positive words, positive behavior, and all that, like stop doing things that can get oneself being hated, or getting into trouble.
