Naturally cooked grandson + arrogant old man = happy to become a fool

Andrews, the Butler: This, sir, is Fräulein Heidi.

Sesemann: How do you do, Heidi?

Heidi: How do you do, Sir Gracious?

[falls trying to curtsy]

Heidi: I didn't do it very well. Shall I try it again?

Sesemann: No, I don't think that could be improved upon.

Heidi: Shall I get ready to go home now?

Sesemann: No. I have another Christmas present for you: a home with us as long as you live.

Heidi: No. I couldn't do that.

Sesemann: Why not?

Heidi: The Grandfather's been waiting for me such a long time.

Klara Sesemann: Oh, Heidi, I hoped you wouldn't want to go now.

Sesemann: But, don't you want to stay here with Klara and be her little sister?

Heidi: Yes. I'd like to be that but I've got to go home.

Klara Sesemann: Papa, I told Heidi you'd let her go if she wanted to.

Sesemann: But you don't understand, dear. You'll be my own daughter. You'll - You'll have clothes like Klara's, everything just like hers, and grow up to be a great lady. Now, wouldn't you like that?

Heidi: No, thank you. I want to go home to my grandfather.

Sesemann: I can't let you do that.

Heidi: But Klara promised!

Klara Sesemann: I...

Sesemann: I'm sorry, Heidi. Someday you'll understand.

[Heidi leaves]

Klara Sesemann: Papa, I did promise you'd send her home.

Sesemann: But dear, you don't know what her grandfather's like. Dete told me that he was a very brutal man feared by everyone. No, Heidi will be much happier here with us.
