Guilty conscience?

I went over to Mandy and Phil's tonight to read bedtime stories. As I'm getting up to leave, I knocked one of Faith''s stuffed animals out of her bed.

FAITH: Uncle Bobb, you knocked Sarafina out of bed!
ME: Oh, I..
FAITH: You bastard!
ME: *flee* *snicker*
MANDY: What did you say? What did you call Uncle Bobb?
FAITH: Uh... a bastard?

So, Mandy yells at Faith. Faith gets, as we call it, a "broken heart" and starts sobbing uncontrollably. Christian notices and starts yelling out of his bedroom.

CHRIS: What did she say?
PHIL: Nothing. Go to sleep.
CHRIS: What did she say?
PHIL: Nothing. Go to sleep.
CHRIS: What did she say?
PHIL: A swear word. Which she probably learned from you.
CHRIS: NoNoNoNo, not me, not me, not me, I swear it wasn't me! I swear!
PHIL: Okay, go to sleep.
ME: Huh. Guilty conscience?
