"Two kids were on the show named Kate and Zack. Their mom had died just a few months, I think, before they were on the show," Jill says. "Because they knew she was dying, they had spent a lot of time together taking trips, done a lot of family things together to pack a lot of time in."
In the show, Kate tells Oprah that one of her most favorite memories of this time with her mother was not the trips, but rather was the time that her mother woke her up so they could share a bowl of cereal at 2 in the morning.
Oprah says that she and Jill still call these disarmingly powerful moments "Cheerio moments."
