[Following a mostly comic interlude about the behavior of Laura's cat]
Laura: Frank, are you maintaining that it wasn't unethical?
Frank: I'm maintaining that it was...
Frank: I'll tell you something. If it were done to me in similar circumstances, I would not be pissed.
Dave: I agree with that. You wouldn't be.
Frank: If you did it to me; if Dave did it to me; if Jean did it to me.... If, on the other hand, someone I didn't know well did it to me, I would be very pissed and that's what's so disturbing about all of this--that you're sort of applying standards as if I'm a stranger.
Dave: Laura wouldn't do it to you, though.
Laura: I wouldn't do it to you.
Frank: But if you did it to me, I wouldn't mind.
Laura: But I wouldn't, Lou.
Dave: See, there are two parts to the "Do unto others." One would say there're one, but there're really two: "Do unto others as others would have done unto you." What does that mean? Well, it could mean, "Do to others what you'd find acceptable if done to you." Another one is "Do unto others what the other would do. And they really are two different things.
Frank: Or the third, "Do unto others as you would like them to do unto you." Which is really what it means.
