Who on this sub has innate perfect pitch?

Just wondering who else on here has innate, not learned, perfect pitch? How old were you when you discovered that you had it? Is it a blessing or curse or both?

I found out when I was around 20. I always had a knack for music: singing, violin, piano, trombone, and a few other instruments, but never really knew until a friend pointed it out to me. Since then, people I know have been jealous, but it’s often a curse because I hear all the bad notes when people play or sing and it’s like fingernails on a chalkboard!

I also can’t explain how it works. When I hear a tone, I immediately know what its value is or if someone asks me to sing a note, the note just boops into my head. I can even do it with chords. It’s actually kind of amazing. I’m pretty sure it’s a genetic thing as well!
