Grandma writes about where she was when planes hit the World Trade Center.
She sees it on the news, then Oskar's mother calls, wondering if she had heard from Thomas (Oskar's dad).
Neither of them have, and they're worried.
Grandma goes across the street to Oskar's apartment and finds Oskar under his bed.
She nervously knits a scarf longer and longer until Oskar's mother comes home.
Mom decides to hang posters of Oskar's dad all over the neighborhood.
After Oskar falls asleep, Grandma turns on the TV and sees the footage over and over again. "Planes going into buildings. Bodies falling" (12.163-12.164) over and over and over.
Grandma writes about the funeral, the one to bury Thomas's empty coffin, and how that night, she has a visitor: her husband has come home.
