The Statuette Robbery

Riddle 
Kushal was alone at home and heard that something had fallen in his wife`s room. He entered and saw that her favourite statuette was broken. At that moment someone ran out of the room.

    Yes, it was. Kushal ran out into the street while chasing a stranger. But eyeglass lenses don`t fog up when a person comes out of a warm room and into the cold. He was just afraid to confess to his wife that he had broken her favourite statuette.
