Dobby: Terrible things are about to happen at Hogwarts. Harry Potter must not stay here... now that history is to repeat itself.
Harry Potter: Repeat itself? You mean this has happened before?
Dobby: I shouldn't have said that. Bad Dobby! Bad!
Harry Potter: Stop it! Stop it, Dobby! Tell me. When did this happen before? Who's doing it now?
Dobby: Dobby cannot say, sir. Dobby only wants Harry Potter to be safe.
Harry Potter: You made that Bludger chase after me?
Dobby: Dobby feels most aggrieved, sir. Dobby had to iron his hands.
Harry Potter: You better clear off before my bones come back, or I might strangle you.
Dobby: Dobby is used to death threats, sir. Dobby gets them five times a day at home.
Harry Potter: I don't suppose you could tell me why you're trying to kill me?
Dobby: Not kill you, sir. Never kill you.
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.
