I like dark beer and coffee, so it stands to reason that I should like dark chocolate, too-- but I don't.
So I bought a bar of it (like 85% cacao or something) a few days ago and have been eating a little bit at a time, just to see if I would acquire a taste for it.
And it appears to work; at first little nibbles were enough to wrinkle my nose, but I just ate a whole square of it and thought it tasted decent. And some milk chocolate I had the other day tasted too sweet.
OK, now you can file this under "random" and go about your day.
