text: Every people have different types of emotions. It's true that they have different kinds of emotions but what if it is fake? Computers are like robots. Computers can't prefer if someone is smiling or upset. Computers don't understand if someone is really smiling for real or faking smiling. It depends on someone's face. For instance, when a friend talk something fun, I smile but when a friend talk something boring, I smile too so they can be happy.
