Your friend Liam was supposed to be at football practice but skipped it to go to the shops. His mum, picking you both up, asks how practice was. Before you can think, Liam jumps in: "Yeah, it was good, wasn't it?" — and looks at you. Waiting. His mum turns to you. "Good session?" Now it's your turn. One word from you and the story holds. One honest answer and it falls apart, and Liam's in trouble, and he'll be furious with you. You didn't skip anything. But you're being asked to lie to back up someone who did. The car's quiet. Everyone's waiting for what you say.
