As a person, I don't really like going to bed early, but I also don't like sleeping the next day away. So, I'm both a night owl and a morning person, but I just kinda end up losing sleep all around. xD (It's not healthy, please don't follow my example here, babs. Get some sleep).
As for in-game (and also in real-life), I love dawn, just before daybreak. It's fleeting, but so lovely.
