Play "how sure?" Take turns saying something you remember from today, such as what someone wore or what time something happened. Before you check, each person says how sure they are: a little, probably, or definitely. Then check. Were the "definitely" answers always right?

Before chapter 5. Danya is "totally" sure Beto cheated. Should he be?

The answer. Not totally. He was ten steps away, behind two players, and the ball hit the raised bump round the drain and jumped up at Beto's arm. "Probably" was the honest answer. Being sure is a feeling; being right needs a clear view and a reason.

Pause to think. Why did "cheat" hurt Beto more than losing the goal?

The grown-up layer. The children make their own rule instead of a grown-up deciding who was right. ThreadForge's Hedda practises saying how sure we are; ShadeForge's Rheo turns all-or-nothing into a dial.

For the ride home. Ask: what is something you are definitely sure about? How do you know?
