Cheryl: Marie, you’ve been so quiet. Are you OK?
Marie: I’m just a little down in the dumps.
Cheryl: Oh, I’m sorry. We’ve been arguing about colors and you’re feeling blue. Hmm. Blue . . .
Paul: What’s wrong, Marie?
Marie: Don’t know. I can’t put my finger on it. I’ve just been feeling ... out of sorts.
Paul: Don’t worry. I can help. Dr. Cheer is here.
Marie: Doctor who?
Paul: At school, people called me Dr. Cheer because I’m always happy and I enjoy cheering people up.
Bob: You know, that’s true. You’re always cheering me up.
Marie: How do you do that?
Paul: I practice laughing every day.
Marie: Laughing at what?
Paul: Nothing. I just choose to laugh.
Marie: You just decide to laugh? I can’t do that. It’s not in my nature.
Paul: How do you know? Just try it. Let me hear you laugh.
Paul: Come on, keep laughing. You’re right. It’s not your personality.
Marie: What now, Dr. Cheer?
Paul: Works every time.
