Friendship: One Mind, Two Bodies

Sometimes, instead of a best friend, you find a girl who should have been born your sister. You share so much with her she knows you better than anyone. You both have the same goals, the same desires, the same thoughts.... She's your soul mate, not just your best friend.

And then sometimes, she goes and does something stupid. Like dies.

And suddenly, you realize you maybe didn't know as much as about her as you thought.
