You're walking home, suddenly you see a little girl crying all alone. You kneel down. "Honey, where are your parents?"

She sniffles and responds: "I don't have any but I live with my brother." In a caring tone you ask: "Can you tell me the address, so I can get you home safe?"

She tells you the address and after a long walk you arrive at her home. She rings the doorbell and a boy your age opens the door. He hugs his sister

"Thank y-" he stops and you realise it's your enemy.
