Stay home with Big Brother, okay?
Big Brother told me. "Stay inside the house, okay? Big Brother will protect you." Big Brother smiled and patted my head.
The room is always warm, and there are many gentle things.
Mr. Rabbit, Mr. Bear, Mr. Cat. I've never seen a real one, but Big Brother buys me lots of stuffed animals.
Big Brother is kind.

A sturdy front door to keep the scary ghosts from coming in. Every day, you watch that large back as he heads out through it.
