From the backseat of the car:
Girl: When I grow up, I'm not going to have a job.
Boy: How will you get money?
Girl: From my money box.
Boy: But what about when it runs out?
Girl: I won't spend it.
Boy: But how will you buy stuff?
Girl: I won't.
Boy (getting frustrated): But how will you buy cages for your animals?
Girl: I won't need cages.
Boy: But how will you pay for a house and food?
Girl: With the money in my money box!
Boy: But what about when it runs out??!!!!
Girl: I'LL USE MY PIGGY BANK!
Boy (starting to cry): That won't be enough to buy furniture!!!
Girl (after a pause, sounding hesitant and a bit panicked): I'll live with Gaga*. She already has all that stuff.
Boy: But what about your family? What about when you get married?
Girl (starting to sound teary-eyed): I won't get married. I'll be like Grandma.
Boy: But you'll get lonely!!!
Me (looking in the review mirror and seeing her hold back the tears): Sweetie, are you okay?
Girl (shouting through full-on sobbing): I WANT TO STAY WITH YOU FOREVER, MOMMY!!!!!
Me: That's fine, sweetie. You can stay with me. [To the Boy] Do you want to stay with me, too?
Boy (with a sniffle): Yes.
Me: Great! We'll all just stay together forever.
