This was the species whose main excuse for not doing something was 'if only I had more time'. Perfectly valid until you realised they did have more time. Not eternity, granted, but they had tomorrow. And the day after tomorrow. And the day after the day after tomorrow. In fact I would have to write 'the day after' thirty thousand times before a final 'tomorrow' in order to illustrate the amount of time on a humans hands.

This is the whole stupid thing about all these unblood relationships. They depend on people staying the same, standing in the same spot they were in over a decade ago, when they first met. Surely the reality is that connections between people aren't permanent, but fleeting and random, like a solar eclipse or clouds meeting in the sky. They exist in a constantly moving universe full of constantly moving objects.

I have been in love only once in my life. I suppose that makes me a romantic, in a sense. The idea that you have one true love, that no one else will compare after they have gone. It's a sweet idea, but the reality is terror itself. To be faced with all those lonely years after. To exist when the point of you has gone.

There is only one genre in fiction, the genre is called book.
