Interpreting Art

I never really thought of formally interpreting a piece of artwork. I have interpreted art through critiques in my studio classes and I suppose in art history classes as well. I know sometimes people see things and meaning in my work that I had absolutely no intentions of. So I think interpretations are nice but sometimes not necessary. Sometimes I paint something just because I like it, not because it has some big elaborate meaning. After reading chapter 1 I am interested in the questions that were proposed on page 1 and 2 and 35-38. I want to learn more about why people do interoperate art and why it is important if it even really is and so on.
