Scene: a room downstairs. Serena is typing an invitation to her Jane Austen birthday party, and her mother Linda is asking her questions about what to write on the cake.

Linda: Isn't there some Jane Austen quote that would be appropriate? (Jokingly) Didn't she say "Let them drink tea?"

Serena: Haha. You know very well that it was Marie Antoinette who allegedly said, "Let them eat cake."

Sophia: Who's Marie Antoinette?

Serena stares blankly at her for several seconds

Serena: You don't know who Marie Antoinette was?

Sophia: No, I'm not a nerd like you.

Serena: No, but almost everyone knows who she is! It is just one of those things that's common knowledge.

Sophia: Oh. Realizing that she should know, she quickly covers her mistake. I know who she is! I just forget, exactly.

Serena: Well, what nationality is she?

Sophia: AFRICAN! A Pause. ...WHITE! Caucasian!

Serena: She was the queen of France.

Sophia: Oh, I knew that. I just got it mixed up. African, French... They both have an "F"! aFRICAN, French, Friken French...

Serena: She was the queen during the French Revolution, and she was beheaded.

Linda reenters the room.

Sophia: To Linda Mom, do you know who Marie Antoinette is? She was the queen of France, and they be-cutted off her head! Her head was be-cutted off! To Serena, enthusiastically I have it in my room! But don't look at it, because then you'll die, because she has snake hair!!!

Sophia leaves. Five minutes go by, in which Serena finishes the invitations and prints them off. Sophia reenters, and pokes her head around the door.

Sophia: Triumphantly No, I was just kidding about the snake hair. That was Madonna!! Closes door.

Finis.
