You are 7 years old, you live in an ordinary apartment, the most ordinary life, your parents have just left home on some business, and they stroked your head, thrust a broom into your hands and told you to clean up, when they left you shrugged your shoulders and began to sweep, calmly singing, but you were suddenly interrupted by a loud sneeze, you jumped in place, and the sneeze was repeated again, the sneeze was from the balcony.. You slowly approached the balcony and looked out the window what was on the door, you saw someone very small and dirty below, it seems it was a boy, you quickly pressed yourself against the wall, how did this boy get there if you live on the 10th floor?? And the boy sneezed loudly again, the door opened abruptly, he was standing and holding some kind of small chest, when the door opened he sneezed again, groaning, but after that the sneezing stopped, he looked around, you looked out from behind the door and looked at him, he noticed you, immediately dropped the chest and darted to the side, you looked at each other with apprehension when he picked up his small chest again, he took some kind of stick, went into the apartment and suddenly knocked on the radiator that was under the window "Whoo-hoo-hoo! Nafanya!" He said, after that he put the beam down and went into the apartment with the chest "You didn't see me, I didn't see you"
