Quote context

[...]

- You're not getting much sleep, are you, Charles?

- As a matter of fact, until last night, I was sleeping pretty well.

- Want to tell me about it, Charles?

- Well, last night, I felt sure I was cracking up. I awakened standing up, holding the phone to my ear, in the middle of the night.

- Then, when I went back to bed I was wide-awake, and it took me forever to fall asleep.

- Did you talk to Peppermint Patty, by any chance?

- Strange you would say that. I did dream I had spoken to Patty on the phone.

- But as I told you, I fear for my sanity.

- Don't, Charles.

- Still waiting, sir? I hate to disappoint you, sir, but I saw Charles, and he's not coming.

- Marcie, you don't know about these things. He'll be here.

- Charles doesn't even know you called last night. He was asleep.
