Sister, Where Are you?

Have you ever wondered what it would be like without a sister? Have you ever lost the person you considered your best friend? Have you ever had a sister? Well, she did. She had a sister but she's not here anymore. Sister's are the most important. Especially if she's the only one you know. No parents included. No brothers, no family. Just a sister. She's dead. She's gone. Will she be back? Will she be next? Would you sacrifice you're life for a dead person?
