A Dark And Stormy Night...

"How far away is your house," you ask. "Oh, it's not that far away. Only a couple of miles from here. You might have passed it," the man says. In a couple of minutes he stops the car and says, "Get out, this is my house. You can stay here for the night." With surprise, you realize that this is the house that you were at before. You can hardly get your answer out as you feebly whisper, "Alright. Thanks for the ride." Now you have no choice but to go into the house. You see that the front door is already open, which is a bit odd. Do you go through the front door, even though it is strange it is open, or try and find a back door.
