Wow, I really wasn't expecting that. It makes me think of my boyfriend, thinking that one day one of us will die before the other. Life can be fucking cruel sometimes. I hope I have the courage of this man and woman when its either my time or his.
The first thing I thought of after reading your post was to wonder if you're a girl or a gay guy. That thought was closely followed by "It doesn't fucking matter."
I'm kinda disappointed that the question came to me at all, though.
