Quote context

[...]

- I seem to have a vague recollection that we had a couple of children. Is that right?

- That's right.

- What ever became of them?

- Rob's gone to school and Peggy's driving downtown with Fred.

- Fred? Oh. Oh, yeah, Fred. Ha, ha. He's a great guy. Oh, yeah.

- All right... There's your breakfast. I have work to do.

- Well, it was nice knowing you, Peggy.

- That sounds like a permanent goodbye.

- You never know.

- You and your wife must come up to dinner.

- That'd be fine.

- Oh, there's one thing more. About that dream I had last night. I've had it before. I'm sorry I had to bother you with it. But you were very kind and you didn't even mention it this morning.

- As a matter of fact, you've been swell about everything. I think they ought to put you in mass production.

- Goodbye, Fred.

- Bye.

- Maybe I'd better wait and see if you get in.

- Ha, ha. Maybe that's a good idea.
