I’m pretty sure my first encounter with ‘real’ art happened when I was in Middle School. I was in the team in charge of our school bulletin board. Someone sent in a poetry, and we were not sure of whether we should pin it, since we could not understand it.
Our teacher said that the only reason we could not understand it because it is poetic, thus we pinned it.
So that’s what art is: everything my lacking-of-imagination brain cannot understand 😐
