The latest one I heard from a male acquaintance was ''You're a mysterious man'' and even ''You are a dangerous man'' lol (which both, just as you pointed out, were said as a compliment AND an insult all-at-once). It got me to think about this.

I've come to the conclusion that even select acquaintances knowing you as a ''mystery'' is not necessarily a good thing. Because most mysteries, at one point or the other, unravel.

The issue is not that you might get figured out, which you probably wont. The issue is that people become desperate to unravel the mystery because they cannot handle the ambiguity and then they start to hang on to every word and spin it in their imagination to simmer along with the existing convoluted fictitious self-made fantasy-story inside their head involving you, creating a perception of you that is very, very far from accurate.

Perception creates reality. And that reality has the potential to come bite your ass later in some unforeseen way or the other because you live in society, unless you have FU money.
