I love Manhattan because it's full of all kinds of life at all hours of the day. Do I expect to see the occasional unusual thing? Of course! It's part of the fun. But I think I would have been surprised to see a sofa some 25 feet above the ground in a tree outside an Upper West Side apartment. For what those residents are paying, they either expect the sofa to be gone or for Hugh Jackman to appear on it, singing tunes from "Les Mis."
