Isn’t it a lovely park? Oh, look at the beautiful flowers, the fresh water pond bisecting the park, the lavish green meadows and a gorgeous peacock in the middle of the park to enhance the beauty of the place even more. You have been here for the last five hours but now it is time to get back home. Wait a minute, there is no one in the park, the possible exit is locked and you cannot see any other way to get out of there. You surely do not want to think about spending the night there and hoping for someone to come and open the exit in the morning. You must do something now and find a way to escape.
