When were you last shocked?
It’s much more likely it was a real life event not an art gallery visit that did it. Real life is far more shocking than any art I have ever seen. A ‘twin towers’ moment, a sudden bereavement, a crime close to home, these are shocking. People hold their cheeks, cover their mouths, are silent or scream. I have never seen that happen in an art gallery.
In an art gallery what emotions are you likely to experience? Perhaps you have been disgusted, or provoked, delighted or absorbed.
