I did not knew for long time that not making eye contact is considered offensive.
The biggest freedom for me is to accept myself and just act as I feel.
Basically your plan - to act like a normie implies the fact that they are higher in social hierachy.
What I do - I disrespect all unwritten rules, and act in normal range, but say what I think and don't give a fuck.
Some of the people like that way and open up too, some of them just back down.
You being yourself without trying to fit into the normal lines is already irritating the people who assume that everybody should fall in line. You know those old people at family gatherings who say the most awkward shit? They have nothing to lose. I like that.
