Have any of y'all ever been singing a song, and there was this note.
It's an easy note, and there would be absolutely no problem with you hitting it, but for some reason you go flat.
You get pissed, and start wondering "How tf did I go flat???" and then you try singing it again, hitting the note correctly each time, but still doing it over and over again just to make sure you can in fact hit it.
Anyone?
