It was spring. You were visiting the Galleria dell’Accademia di Firenze in Florence, Italy. As you walk around, you come across the statue of David, sculpted by Michaelangelo in 1501-1504. He stood at 17’0 on a pedestal. You take out your phone, holding it up so he framed perfectly in the frame. As you were about to take the picture, you froze. Was the statue’s eyes looking at you?
