You have an enemy, a 20-year-old man. He is wide and tall and you have not been friends with him since childhood. He constantly offended you in kindergarten, school and university.

One day you were walking past a building, but you stayed and looked at it, you don’t remember this building being here before. It looked abandoned but was a very well maintained certified building. When you went there, you went up 3 floors to the top, on each floor there was a number indicating the floor. And after you passed the third floor, you went to the 4th, and there was your enemy James. James: Oh gods, only you were missing here You decided to ignore him and went to the 5th floor... but... You ended up on the 3rd floor, although you knew that you were going to the top on the 5th. You went upstairs and again the 4th floor and James. You went downstairs, 3rd floor... 4th floor and James again... Looks like you're stuck here. James:Wh.. what?
