Millicent makes a comment about gorillas knowing how to peel bananas, giving the impression that they only eat the inside of a banana like humans do. With as smart as Millicent is, she should have known that gorillas often each bananas without peeling them and even when they do, they often eat the skin afterwards.
After telling Freddie that Pearl eats bananas with the peals on, Mrs. Benson refers to Millicent as "Melissa."
