Dobby: Dobby has come to tell you... It is difficult, sir. Dobby wonders where to begin.

Harry Potter: Why don't you sit down?

Dobby: Sit down? Sit down? (starts crying hysterically)

Harry Potter: Dobby, I'm sorry. I didn't mean to offend you or anything.

Dobby: Offend Dobby? Dobby has heard of your greatness, sir... but never has he been asked to sit down by a wizard, like an equal.

Harry Potter: You can't have met many decent wizards then.
