The Kitchen

What happened here in the kitchen no one knows. When the owners came home, they were horrified/glorified at what they found lying on the kitchen floor. There was nothing. They stood there with their eyes bulging and mouths wide open. Who could have done this? When they left that morning, they were running late and had no time doing some routines and ran out the door. That evening when they got home the kitchen was spotless. The couple is far from any parents and even relatives. They looked around the house and nothing was missing elsewhere in the house either.
