Meh, shoulds. For the first six months or so when I moved out on my own, I probably didn't eat anything more veggie-like than mushrooms and hot peppers because my folks had told me to do otherwise for a good long while. It was just a bit confusing when my body first requested veggies after that - by way of an unexplained food craving that I had to walk through the nearest grocery store's produce section, sniffing the food, to nail down. (Target turned out to be raw cauliflower, which I didn't realize had a smell before that.)
