Nothing about me is unique or even particularly interesting.
No matter how bizzarre or eccentric something about me seems, there'll always be others who share that trait, and several others as well
One in a million means that there'll be 6,446 others like that one, enough to fill a small city.
What makes me unique is that the combination of traits I have, statistically speaking, will be far rarer.
I would hope that that makes me unique, and certainly there're none quite exactly like me. Whether there are some too close to tell, well, I'd hope not.
But eh, anywhen some traits that are relatively rare about me:
Conlangs/linguistic obsession
Map obsession
Aviculture/flying things/dinosaurs obsession (though judging by the titles at least one here shares this with me)
My dreamworlding isn't really out of place here, but in the real world it is
I have some other things, but they took me off on a tangent so I've removed them.
