- Now I'm wide-awake. It's time to get up.
- Good grief, it's 1:30 in the morning. What am I doing up at this unearthly hour? Maybe I'm dead.
- I wonder if I'll ever fall asleep again. Maybe this is it, never to sleep.
- Good morning, sir. You're up early.
- You'll never guess with whom I had a heart-to-heart talk.
- You didn't call and bother Charles, did you, sir?
- What do you mean, Marcie, bother Chuck?
- Last night, Chuck offered to take me to a movie or something. And I'm waiting for him.
- Of course, I'm just being polite.
- No mushy stuff for me, Marcie.
- If Chuck gets too fresh, I'll deck him.
