I got my sister banned from clubpenguin
Why did you get her banned from the game?
Because she's terrible at it.
Teach your sister how to play. She could end up better than you on that game.
No way, that is impossible. She sucks at Club Penguin.
It's not very nice to get her banned just because she's not good at it. If she enjoys it, she should play whether she's good or not. Eventually she's sure to get better, too.
