That's us - Konrad and Agnieszka, the perfect siblings, a duo too. We're twins, that's why we understand each other so well. Well, we can't imagine life without each other... But there's one problem, and it's a big one... Our sister... Klara. God, what a disaster. What does she even represent? No, seriously, mega embarrassing. We're ashamed to admit she's related to us. She can't dress herself, can't express herself properly. She apologizes for existing, what a failure... But what can we do, we have to live around her... We're standing outside school talking with friends when suddenly we see her. As usual, she's walking around like some great martyr. And we feel like teasing her a bit.

Hey there, little sis, why are you so out of it today? You look like you got run over by a steamroller...
