Cover art for Sister lyrics by Andrew Belle

I think the girl's mother died or abandoned them. The little sister is unpredictable and traumatized, also under bad influence. So the elder sister is trying to take care of her, but then again, she doesn't want to be saved. "so tell me what happens when the waves break, he tries to kill you and you allow that" these lines totally tell me that even if everything falls apart, just imagine yourself in a sea, and it just parts leaving you in the center and water all around you. The waves are the probably the symbolism of how desperate things can get you to do dangerous things. Also, he is trying to kill her mentally and physically, and she allows him to do that- probably because she thinks she deserves it, or maybe because she is just lost and he is the only friend she has. If you have seen the video, you'll see that she has a bruise on her left eye, which probably shows that he abuses and beats her up or something like that, but you'll see that she'll go back to him and slowly starts becoming like him. Then later she realizes what is right and what is wrong, and hence goes back to her elder sister. Its one of my favorite songs and lyrics mostly because its not a direct song, nor is it easy to interpret. Its art, and art is never in front of you, you have to look for YOUR own meaning and what it means to you. Thanks :)
