Extend the Story - Add a Room

You curse as you enter the kitchen to see that your mother's favourite serving platter has fallen from a kitchen shelf. Confused, you begin to sweep up the shards of china littering the kitchen floor. Suddenly you feel something furry brushing against your thigh. A familiar meow comes from this furry creature. "Jeez, Missy," you scowl at your cat, who is looking up at you guiltily, "What were you trying to get to up there?". But Missy struts off and disappears through the cat door. Inspecting the shelf, you cannot find anything out of the ordinary. But something in the kitchen just doesn't smell right. In fact, it reminds you of...

Milk that's been left out of the fridge for too long.
