One day four friends went to an apartment that was haunted. Every villager said that if you go to the rooftop a ghost will push you off. The four friends were very curious. The played rock, scissor, paper to see who would go to the roof. When the friend who lost arrived the rooftop he would let the others know if there was a ghost by signalling to them. If there wasn’t a ghost they should look down and make an “X” with their forearms. If there was a ghost they should look down and make an “O” with their arms . 

When the boy who lost arrived at the rooftop there was nothing so he looked down and made an “X” with his forearms. But when he looked down his friend’s faces were shocked and they made an “O” with their arms.
