"Not so long ago, Jules lived in a very small house. The kitchen was in the living room, the bed in the library, the bath in the kitchen..."
Jules and her parents were so cramped that they moved out. Now they live in a big house. There are so many rooms that Jules doesn't have enough fingers to count them all.
But Jules is bored: nothing amuses him anymore, not even his moustache collection. Until one day, when the simple act of making a paper airplane allows him to meet everyone in the neighborhood, including a little girl his own age.
