Quote context

[...]

- I understand you're confusing gratitude with affection.

- You have no right to speak to me like that. How dare you!

- I'm sorry. It's entirely your own affair and nothing to do with me.

- Nevertheless, I still think you should leave here. Believe me, it's for your own good.

- Really, Paul, I can't imagine why you make this idiotic request.

- It is not a request. It's a demand. You must not stay here.
