Your toilet paper situation mapped to programming logic—because nothing says "existential crisis" quite like checking if something exists before using it.
Non-zero value: There's actually paper on the roll. You're living the dream.
0: Empty roll still mounted. The classic "technically present but utterly useless" scenario—like having a variable initialized but with no meaningful data.
null: Empty roll removed, holder exposed. At least someone acknowledged the problem existed and cleared it out. Respectful.
undefined: The holder itself has vanished into the void. Did it ever exist? Who knows. This is what happens when you forget to declare your bathroom fixtures.
The hierarchy of desperation, perfectly visualized through bathroom architecture and type coercion.
