Gerard's never really been lucky. He's late for everything, he stutters whenever a hot guy even breathes near him, and he's famous for always managing to get caught in the rain. Even tripping over his own feet is just an accepted part of his everyday routine by now.
Because of Gerard's shortage of luck (and seriously lacking social skills) it comes as no surprise to him when he manages to embarrass himself in front of the Sixth former that he's been crushing on, like, forever. So in true Gerard style, he bolts in the opposite direction and doesn't look back.
