- You know, in the bottom of my heart after thinking it all over, you're so right. That blouse was awful.

- Oh, no, not awful.

- Yes, it was!

- Of course, I wouldn't admit it at the time, but what woman would? We hate to admit we are wrong. That's why we're so feminine.

- Oh. Well..

- You know, this is the first time you've shown a little sense. Quite a change in you, Miss Novak.

- I know it, Mr. Kralik.

- Now, if you just keep this up and I think we'll be able to get along much better.

- Thank you, Mr. Kralik.

- Quite alright, Miss Novak.

- You know, I was planning to wear that awful blouse tonight. I have a date with...

- Oh, didn't you hear what Mr. Matuschek said? We have to stay here and decorate the windows.

- Oh, that was such an obvious trick. I almost fell for it, too.
