text: Lets say you were sad one day and going to get a panting done, when you showed up you looked happy but on the inside you still were still sad. on the outside they can see or show any emotion, when you get throght the walls of pain created by yourslef you are the only one who really knows what is wrong with you. The second paragraph said "Can we really calculate emotions like math homework...and can a computer reconize the subtle facial movements we humans use to express how we feel". meaning can technology really tell how a person is feeling. or can it tell the right feeling we are having.
