I was pretty impressed during the opening of one of my shows, when the five-year-old daughter of a well-known movie actress took a running jump at one of my paintings, like she was diving into a swimming pool. I preferred to treat her impulse as a compliment rather than insult. Sadly she hurt herself more than the painting.
Hopefully, as I get older in the business, I make my choices more accurately, and I perhaps know from either the script or the first meeting that it isn't going to work.
