Do you like chocolate? Maybe most people do. A box of it can be a great gift. Buy one for a friend and give it as a surprise. See how happy that person gets.

Say you just got a box of chocolate. Which piece do you pick first? A man has studied people’s choices. He says they tell something about the person. Did you choose a round piece? You are a person who likes to party. Did you choose an oval (椭圆形的) shape? You are a person who likes to make things. Picking a square shape shows something else. The person is honest and truthful. You can depend on him or her.

What kind of chocolate do you pick? Maybe you like milk chocolate. This shows you have warm feelings about the past. Dark chocolate means something else. A person who chooses it looks toward the future. What about white chocolate? Would you choose it? If so, you may find it hard to make up your mind. Some people like chocolate with nuts (果仁). These are people who like to help others.

Do you believe these ideas? Can candy tell all these things? It doesn’t really matter. There is one sure thing about eaters of chocolate. They eat it because they like it.
