Quote context

[...]

- Go on and dance, my heart, this is romance, my heart, so keep pretending. (2)

- Do not despair, my heart, we still may share, my heart, that happy ending. (2)

- If it's to be, we soon shall see, and if it's not to be, no power on Earth can make it so.

- You know it's spring, my heart, go on and sing until we know.

- Oh, I brought you something.

- You're always so nice to me.

- Nice? But you are my nicest boarder.

- Well, no matter what you say, I'm not going to pay you a cent more.

- Oh. Who wants more money? I am so happy you are here.

- You're always happy. What's the secret?

- Oh, I don't know. I don't know. My place is half empty, I have rheumatism, and my husband left me with five children and they're all ashamed of me. I don't know.

- Oh, I'm sorry.

- Oh, you shouldn't be sorry, you should be happy. There is no boyfriends calling on you so you don't get married. And if you don't get married, your children won't be ashamed of you.
