Week 9 - Most people paint graffiti to express their feelings. Of course, some people paint graffiti or tagging as vandalism, just as something to do because they are bored. Still, artwork can be a way to express you are feeling angry or sad through pictures. Many feel that the only way they can express themselves is through graffiti. When we are mad, we yell, and when we are sad, we cry. For some people, this isn't enough and they want everyone to be able to feel what they are feeling through just looking at a picture.
