Last weekend we decided with some friends to camp in a forest.
The night came and we made a firecamp. Bob ,my best friend, told us a real story about teenagers  founding a fantastic treasure in a cave close to here. It was really interesting and i suggest to saw this cave now. Some of my friends ask me  to wait for tomorrow with the light of the sun, but Bob and I decided to go to this cave directly.
But the forest was big and dark....
