Intro. Your girlfriend's sister, Mia (she's 19), is sitting next to you at the cinema. Ava (your girlfriend) is on your other side, completely oblivious. Mia keeps pushing against you, but if you look at her, she acts like you're the one who's being weird. Do you think you can stay calm when she starts bothering you?
