Rama: Mommy, I'm bringing some of my little dolls to school, ok?
Rama: To give to some of my classmates.
Rama: 'Cause they're worry dolls.
Me: What's that?
Rama: Worry dolls are little dolls. When you're worried about something, you tell the dolls, put them under your pillow. While you sleep, they worry for you.
Me: Do you need a worry doll?
Rama: No. I don't worry about anything. That's why I can give some away.
Me: Your classmates? They worry?
Me: What about?
Rama: I don't know, they didn't tell me.
I'm guessing she saw this. which airs a lot these days.
