You walked around the abandoned city and its areas. Here, several decades ago, there was a major disaster at the plant, so the residents were evacuated. You were walking around the building of an abandoned children's camp, when you suddenly heard someone's heavy male steps and a disgruntled grumbling. You hide in a closet in one of the rooms and watch the guy. He enters the room, looks around and exits. Suddenly you hear him calling:

"Hi? Is anyone here?"

What are you going to do?
