Code-dependencies Memes

You touch ONE line of code written by Steve from 2003 and suddenly the entire application is held together by prayers and spaghetti logic that defies the laws of physics. Every dependency is connected to seventeen other dependencies, none of which are documented, and the original developer retired to a beach in Thailand with no forwarding email. You're just trying to fix a simple null pointer exception but NOOOO, apparently that bug was load-bearing and now the authentication system thinks it's 1970 and the database is crying in a corner. The code has more nested if-statements than this wire mess has cables, and somewhere in there is a comment that just says "DO NOT TOUCH - WORKS, IDK WHY." Good luck untangling that nightmare without bringing down production. Godspeed, brave soul.
