I agree with "Love is like wine." Both can be light or dark, depending on your mood; they're both intoxicating and are beneficial to your health in daily doses; they both can deepen and become better with age (or sour and become an awful vinegar).
Hit me with the Martial stuff, that's fine. Funny thing about that poem--it could also be used to describe a very young woman.
I haven't read any DD/SS/HP but it sounds interesting. If you know of a good one, feel free to pass the rec on to me.
