A complex story is behind every silent person

Everybody in life has a different story. Some are sad, others happy, and some in the line of grey. Each and every one of these stories craft a unique character, different from each other, due to the causes in his life, and his senses. The senses have an integral part in shaping hobbies and dislikes; one might be intrigued to learn the piano from the large area fo emotions it can cause. A person whom doesn't talk much, is probably the most thoughtfull. However, that does not mean he has a more complex and difficult story than others; it simply means that the others have not discovered his story. That creates curiosity, which makes the story seem more interesting, all the while this person thinking of wether to express his opinions or not. He could change the way people see him;but why get a label? Why is there a need to place a label on someone? Can't a person be gray and not white or black?
