- Ellen, where are you? Oh, here you are.

- Yes, Miss Cathy.

- Has Mr. Linton gone?

- He just left.

- Oh, Ellen, I have some wonderful news for you...

- Well, the kitchen's no place for that dress. Come inside.

- No, no, listen. Edgar has asked me to marry him.

- What did you say?

- Well, I'm to give him my answer tomorrow.

- Cathy, do you love him?

- Of course. Why? Now, isn't that a silly question?

- Because he's handsome and pleasant to be with.

- Not enough.

- Well, then, because he'll be rich someday! And I'll be the finest lady in the county.

- Oh, Ellen, it would be heaven to escape from here.

- What about Heathcliff?

- You know he gets worse every day.

- It would degrade me to marry him. I wish he'd never come back.
