Quote from Sally in Portrait of Tommy as an Old Man
Don: I got your message. Sally: I saw you being interviewed on the news today. The camera loves you. Don: Yeah, well, I've been working on a big case, Sally. A case involving murder. Sally: Murder, Don? Don: That's right, Sally. Murder with a capital "M." Sally: Unless it's in the middle of a sentence. Then it's a small "M." Don: Yeah, yeah, that's right.
