Lol, "high quality people", that's inventing classes & intolerance where it's not needed.

So if I speak a language the other party doesn't know (even tho I know their language & can speak it) I'll be able to get a good thing going?

Social disguise does not exclude being completely honest. That is a separate thing!

Also you think ppl are dumb & can't differentiate between social masking & what the words that I'm speaking mean?
I connect well with ppl listening to the meaning I try to convey, it's way harder with ppl that take your social vibe into consideration (bcs now I have to modulate that as well as my words to get the same meaning across).

You will turn away high quality people who can see through your disguise . . .

The "disguise" as you call it isn't a secret, it's meant to be understood & looked-through. That's how all deeper relationship work bcs even what you would call "no disguise" (which imho isn't a thing bcs we learn cultural norms, we aren't born with them) works just as a disguise bcs the limits of communication are just so vast.
