This is a new house and you have never been in this house before. You have come here on the invitation of your friend. You friend has left you inside the house and has gone to the market to buy some things but it has been hours since he left and he has still not come back. You try to go out of the house to go to the market and look for your friend but the exit door is locked. There should be a spare key somewhere inside the house and you must find that key to open the door and go out. Do it quickly.
