You cannot convince me the cullens wouldn't CREATE. In every sense of the word. That Alice wouldn't have a sculpture of light on her wall, woven from strands of Christmas lights, odd bulbs, strobing colors, living on her wall, breathing with her, as she fades in and out of awareness as time wanders slowly by. That Edward wouldn't have binders full of his own musical compositions, piano arrangements of his favorite symphonies that he arranged just for himself. That Emmet wouldn't build a car up from nothing. That Carlisle wouldn't publish literature. Not novels for entertainment, but true, pure literature. He has so much to say. And you cannot convince me that Esme has never gone out and woven the exact textile she wanted her couch to be made of, because she had a vision, a passion, endless time, endless resources to create what she felt in her heart. That Jasper never sought to make Alice a piece of jewelry instead of buying her one.
It goes on and on, but I only believe that where human people say "I'd love to create that, but it's not worth the time and money," the cullens would say "I'd love to create that, and the cost of buying it, the 40 hours of satisfying occupation I lose, is a hefty price"
