The process of returning home revealed quite a lot about Le Corbusier’s character. If the work went well, if he enjoyed his own sketching and was sure of what he intended to do, then he forgot about the hour and might be home late for dinner. But if things did not go too well, if he felt uncertain of his ideas and unhappy with his drawings, then Corbu became jittery. He would fumble with his wristwatch – a small, oddly feminine contraption, far too small for his big paw – and finally say, grudgingly, “C’est difficile, l’architecture,” toss the pencil or charcoal stub on the drawing, and slink out, as if ashamed to abandon the project and me — and us — in a predicament.
