Quote from Phoebe in The One with All the Cheesecakes
Monica: Can I talk to you for a second? What are you doing? Phoebe: I have plans with Joey. Monica: So? He'll understand. Phoebe: No, he won't. And that's not even the point. Monica, I made a whole speech about how you do not cancel plans with friends. And now, you know, just because, potentially, the love of my life comes back from Russia for one night I should change my beliefs? I should change my beliefs! No. If I don't have my principles, I don't have anything. Monica: God, you are so strong. Phoebe: Or I should rush through dinner with Joey and I could meet David at 9.
