'It just isn't fair,' thought Susie. She's not much younger than Jack, and she's just as good as him at running and climbing and swimming, oh, at everything really. She's as good as him or any boy and she's worth at least ten of that pathetic Barbara so why, WHY wouldn't they let her join their club? It could just as easily be the exciting eight or something, but no. Her brother and his friends had to have their stupid secret shed and their stupid password and all their day trips and excursions that she isn't allowed to go on because she's not a member.
Well, she'd show them. She'd do something so amazing that they'd HAVE to let her in. They'd be sorry then.
