My friends and I once (as in, one day...) went stealng bread from doorsteps in Germany, until we tasted one that was so ...different... to what we considered to be 'bread', we never did it again. Black bread? 'Different', meaning 'absolutely disgusting' to [our] tastes, at that time.

Our tastebuds have to learn to appreciate new tastes. So if you grew up on a very sugary taste palate, having dark bread for the first time will be tough. If you were unlucky enough to pick one with added caraway I'm not surprised at all. That has some strong and somewhat bitter taste and serves you right for stealing it xD
