Amy. Where to start with her? That girl is so disrespectful to her sister and disobedient. That poor Sammy just doesn't deserve it. Luckily, their parents like Sammy a lot more than Amy. If they didn't, I'd imagine how they'd introduce them to other people. "This is our daughter Amy. This is our other daughter, Amy's sister." Should've just had Sammy and bought a dog.
