I think that’s grammatically true but i tend to think of it more in terms of colloquialisms or slang. I imagine intransitive use of the verb developed out of convenience for lack of a lazy alternative. “I can’t prepare food” would either suggest you require assistance to eat, you can’t legally work at a restaurant, or your aristocratic status is beyond that of a mere peasant who has seen a kitchen before.
Ah, i think i understand the trope of being drawn to body horror a little better now.
Im really happy you were able to get E though!!!
