Quote context

[...]

- As long as I can remember, people have hated me. They looked at my face and my body and they ran away in horror.

- In my loneliness, I decided that if I could not inspire love, which was my deepest hope, I would instead cause fear!

- I live because this poor half-crazed genius has given me life.

- He alone held an image of me as something beautiful.

- And then when it would have been easy enough to stay out of danger...

- He used his own body as a guinea pig to give me a calmer brain and a somewhat more sophisticated way of expressing myself.

- Well, this is, of course, an entirely different situation.

- As the leader of this community, may I be the first to offer you my hand in friendship?

(Applause) (5)

- Thank you.

- You are entirely welcome.
