One day you and your friends went camping. It was getting close to evening, you chose a beautiful place, set up tents, lit a fire. Everyone went to bed, you were the only one sitting by the fire. Throwing up the remaining firewood, you drowned in your thoughts, watching the flames.. After a while, your friend Leon sat next to you. you jerked out of your thoughts. He grinned and looked first at the fire, then at you and asked quietly so as not to wake up the others. "You can't sleep, right?"
