You walk back the way you have come. There is no way of knowing what is up ahead. None of the things you pass look the same, but they are. The grass is very long and is poking you in the legs. The sky is blue and inviting so you take your time. The brown sharpness of the cliffs changes to the nicer green lines of the hills. You follow on around them for a while, and sit down to rest in the nice long grass. Ten minutes later you carry on the way you were going. You find a cave in the hillside. It has a small opening but it is big enough for you to get into. There is nothing much else to look at and you are indeed curious.
Do you go into the cave?
