Pulled one string and the whole thing moved A dependency I never approved Following breadcrumbs through the stack Each one pointing further back Version numbers wearing thin Every patch a paper skin Someone wrote this years ago Left a comment: "I don't know" Loose thread, loose thread Following wherever it led Past the last commit, past the dead End of the line, or just ahead The clock says four, the hallway's dark Only sound's the server's heart Somewhere in a foreign port Something listens, something's caught Loose thread, loose thread Following wherever it led Past the last commit, past the dead End of the line, or just ahead And the beautiful thing about a thread this long Is you forget which end you're holding on Still pulling Still pulling
