Popular quotes from Harry Potter and the Half-Blood Prince

It was, he thought, the difference between being dragged into the arena to face a battle to the death and walking into the arena with your head held high.
It is the unknown we fear when we look upon death and darkness, nothing more.
Once again, you show all the sensitivity of a blunt axe.
You are protected, in short, by your ability to love!
