At first I thought you had a scary photographic memory only really exampled by this girl in the second season of ReGenesis wearing a cerebral helmet thingy after she ate chicken infected with mad cow disease.
But then... wow, don't stare so long. I mean really, it's not hard to tune things out. Voices are really enough, images are then left to the imagination. If you have to use your eyes then you can't use them to read whereas listening can be multitasking and is safer.
Cause I keep my nose in a book and I'd be all "cute sisters" and that'd be it :p
Btw, ORANGE SHIRT? Please post a pic. From a catologue or something.
