Pidge never really did like those kind of proverbs and also she's not thinking 100% straight at this point, which is why her train of thought veers off into pedantic land.

"Of course it is. You don't eat the non-fruit bits of a fruit-bearing plant. Fruit evolved to be sweet so that animals would want to eat it and spread the seeds. There's no reason for a plant to want an animal to eat the actual body, so it's bitter...Nnnnnot sure how this relates to patience anyway."
