People can be like those Kinder Eggs they used to ban in the United States (for some unknown reason). On the outside, you're getting something you think you know. A person might be small, appear timid, or made out of chocolate. It's the inside, however, you need to be wary of. Sometimes a person might be more talented or dangerous than you realize, and the other times they'll probably just embarrass someone who deserves it with those hidden talents.
