Oh boy do I resonate with this. Thank you for sharing this!
I remember the first time I saw "Fountain" by Duchamps, which, for the uninitiated, is a urinal, on its side, signed and dated by the artist. For years, decades, I cast it aside in my mind as something silly, something artsy, something that wasn't for me. It was ugly, vulgar, and above all, obvious. For years, seeing replica after replica in modern and contemporary art museums, I continued to breeze past the installation, laughing quietly to myself like I knew something these art people didn't.
Then I had a similar situation happen. While continually saying "anyone could have done that" and "this isn't art" someone finally said to me "yes it is art, you didn't think of this, and without this, you lack the basis for many other contemporary forms of art." It then started to occur to me that this art was anything but obvious; if I so easily cast this aside as "not art," the simple fact of calling this art was a profound statement, one worth considering within its context. Maybe this piece of art had so much to teach me about perspective, context and expression that it was just too much to swallow for years.
