When I was eighteen, I skipped out of one of my college lectures and joined a buddy in his art class. Being bored I began drawing. Half way through the lecture, he says "cool, finish it."" What are you talking about? "That picture, it's not done."Now flipping through his book, opening it to Edvard Munch's The Scream. He was right, I forgot 2 shadowy figures along the fence line.

Thanks for the trigger!
