These people stopped me at a train station at started singing?

So it turns out that I'm a legend to them all. Every son and daughter
is safe from you-know-who all because of when I was small.

Long story short, this guy Voldemort was super cruel. He tried to kill
me and my parents, and this is where it gets intensely cool. Even
though I was a tiny little boy, my parents died BUT I survived and
then destroyed this evil guy and it's a story some people enjoy to
tell.

And it's all so sad, I mean, my mom and dad were killed long ago. And
I wanna be psyched but being unliked is all I know. I never thought
I'd be a part of such a fate, an opportunity eleven years late... and
I guess it's time for me step up to the plate and show 'em that I'm
something great!
