But everyone makes mistakes. As long as you remember where you went wrong, you won't make the same mistakes again. [And it's obvious that Hiro won't be forgetting this mistake any time soon. Not with the way it's apparently been weighing on him.]

Anger isn't wrong unless you turn it on another person. [A sad sort of smile.] You won't be like him, but you don't have to be like me either. Just be Hiro.
