Look Up! Look Down!
The OP decided to view what an abandoned orphanage looked like from the fourth floor for some unknown reason. The previous guy may have gotten out of there significantly worse than he was. They were only a single step away from falling into a massive hole in the floor that would have dropped them four stories down.
Only when they thought they were safe did a group of bats suddenly appear from nowhere to terrify the OP. Do we guess this means the person in question will assume the role of Batman in real life?
