What would you do for your best friend?

My best friend is my sister. I have other really good friends, but she is my sister. I would do anything for her. I will always do anything for her. Whatever she needs. I love my sister more than anything, and I will always be there for her whenever she needs me. I honestly would die for her, although I hope I never have to, because I wouldn't want to leave her. There is nothing I wouldn't do for my sister.
