Guy: Hey, you`ve been reading that book for a long time.
Girl: It’s a good book. It’s my dad’s. He already finished it. He’s reading mine.
Guy: What’s it called?
Girl: Children of Cain.
Guy: What’s Cain?
Girl: I don’t know. Dad?
Dad: I think it’s from the Bible.
Guy: Ah.
Mom: Cain was from the Bible, he was one of two brothers. And I believe he did something naughty.
