What Do You Mean What Am I Doing

The senior dev watching the junior write actual readable code with proper variable names and comments is experiencing what doctors call "psychological damage." After years of maintaining legacy spaghetti where variables are named x1, temp2, and theRealFinalVersion_actuallyFinal, seeing someone follow best practices feels like a personal attack.

That look of confusion mixed with existential dread? That's the face of someone who's been writing if (x == true) for a decade realizing they might have to adapt. The junior's just vibing, writing clean code, probably using meaningful function names like calculateUserDiscount() instead of doStuff(). Meanwhile, the senior's entire worldview is crumbling because someone actually read the style guide.
