William is neither homeless nor deranged. He works as a real estate agent and walks around in a suit, which is perhaps why he turns so many heads every time he enters Washington Square Park and is immediately covered in pigeons. He knows the birds, they know him, and every day during his work breaks he stops by to visit them. For the average passerby, fraternizing with pigeons is often seen as an activity reserved for the dirty or the insane. Being that William is neither of the two, the next most logical explanation is that he simply loves animals.
