Possibly interesting factoid: my father and I share barely any food tastes. I love vanilla as intensely as he hates it. He likes his alcohol dry while I like mine sweet. At the same time he tolerates crappy sweet snacks and poor quality chocolate that I would find cloying after the first bite. I'm okay with import fresh produce while he can't stand anything out of season or greenhouse-grown or non-organic. Both my parents seem to like fish quite well, and eat everything with lots of slices of bread, whereas I can't stand either. I once bought some green tea only to discover I utterly hate the taste, while my father was pretty glad to have the green tea all for himself.

I wonder what might be going on...
