We arrived last night at Allison's parents' place for the holidays.
This morning, upon waking up, Allison took our dog Rosie for a walk. When they came back, Allison vaguely noticed that the small SUV outside the house was black, and she thought that her parents' car was silver. But they walked past the car, went up the steps on the porch, walked across the porch to the front door, and when they were about to open the screen door, they noticed that the front door was open, but they had closed it.
It was then that they noticed they were walking into the wrong house.
