Chiu makes this analogy: Her friend's child is very thin, and has never been a good eater. Later Chiu discovered that "the reason why he didn't want to finish his first bowl of rice was because it would be followed immediately by second and third bowls."
邱守榕比喻說，有個朋友的孩子很瘦，一直不願好好吃飯，後來才知道他不好好吃完第一碗飯的原因是，「如果第一碗飯吃完，第二、三碗馬上又來了。」
