"I went with my friend, Oliver," he said. "We were there for a week and did very little. We weren't active tourists. We walked to the restaurant each day and stumbled back from it at night. Playing cards, reading books, eating tomatoes, staring at the view--that was it for a week. It was great. Then we ran out of books. We had nothing to read and there was only this really shitty news-stand. We were like, 'Urgh, that sucks. We should totally open a bookstore!' "
