All the light switches in the hallways were timed to go off after ten or fifteen seconds, presumably as an economy measure. This wasn't so bad if your room was next to the elevator, but if it was very far down the hall, and hotel hallways in Paris tend to wander around like an old man with Alzheimer's, you would generally proceed the last furlong in total blackness, feeling your way along the walls with flattened palms, and invariably colliding scrotally with the corner of a nineteenth-century oak table put there, evidently, for that purpose.
