I'm new to this website. What goes on here?

Life goes on and on

A man lives on the tenth floor of a building. Everyday, he goes on the elevator and goes down to the lobby and out the door to work. At the end of the day, he goes back to lobby, and goes up to the 7th floor, then walks the extra 3 floors, unless its raining, then he goes up to the 10th floor. Why does he do this?

He gets more deranged as the video goes on
