You are facing towards the mirror right now, exit the washroom, turn right, to the left you can find a chair, go near the chair, infront of you there is an opened door which leads to go outside the house, which is left to the stair case, go near the opened door and step out of the house, turn right, you can find a glass window, enter through that glass window, to the left you can find a white car, that would be your end point.
