Rosa: So this is your car?
Ace: Yeah, I've had "Old Faithful" since I learned to drive.
Rosa: Overheats that often?
Ace: Heh. Only when it's not raining.
Rosa: Ace, you're no fool. You know part of the reason I ask for you to escort me was to check you out for my granddaughter. Would you like to take her to see that spaceship movie?
Ace: Isn't that her call?
Rosa: She messes with my love life, I get to mess with hers.
Ace: Well, if she wants to go, I'd be happy to take her.
Rosa: You're a good boy, Ace. Drive home safely. You'll understand if I have her pick you up. - (Thinks to herself) Yeah, I still got it.
