Quote from Diane in Affairs of the Heart
Sam: The line's busy. Cliff: Oh, that means she's calling an ambulance, huh? Diane: Cliff, now stop it. We don't have to jump to conclusions. Look, a lot of people when they're having a romantic evening, they take the phone off the hook. They don't want anyone to interrupt their intimacies. Sam: How come we never did that? Diane: I might miss an important call.
