Funny, one of those dire situations that a character makes light of. I like those. I also liked the line about the lamppost/ door choice. Good job, and great first story! Welcome to the wonderful world of Ficly.
I like it. At first it felt a little too straight-forward and dry, but by the end it reads like a semi-panicked but trying to hold it together, which works for the situation. The situation is interesting, that it’s completely dark (okay, thinking cave), but then he figures he might hit a lamppost or doorway (so some kind of pitch dark post-apocolyptic thing?). Whatever it is, it made for a fun read.
