I used to be as a teenager, but since I came to uni and started eating out with friends (notice the 'with' in that sentence, deviants
) I've sort-of realised it's annoying and a bit silly.
That said, there are some tastes I still hate - mushrooms, strong garlic (I hate garlic bread, but don't mind garlic used in sauces or something where it's not the main flavour), cherries...
