It's true; I have a similar thing with music.* I can play any
instrument, have perfect pitch.* TOTALLY useless talent for me,
but I have it.* I can't understand someone who can't
discriminate each of the instruments in a band or orchestra and
hear them playing separately, or be able to tell you what note a
refrigerator motor is playing and all of it overtones. Some
things you can just "do".* Some things are a struggle.* For me,
I think it was an overcritical 3rd grade teacher that made me
go, "forget it, can't draw' and it stuck with me.
