My mother did not eat vegetables. The only exception was potatoes and even then it was usually in the form of McDonald’s french fries. Every other vegetable she despised. My sister was quite similar because she blindly aped what my mom did most of the time.
Vegetables have such extremely varied tastes and textures I am absolutely convinced that hatred of all vegetables is some form of mental malfunction and has nothing to do with gustatory qualities or anything else. A bell pepper is nothing at all like an olive and both in no way resemble a quality tomato.
