Your immune system is basically that paranoid friend who sees danger EVERYWHERE! It's like "Hmm, this peanut looks suspicious... ATTACK!" Meanwhile, your own cells are like "We literally BUILT this body" and your immune system goes "SOUNDS LIKE SOMETHING AN IMPOSTOR WOULD SAY!"
The real kicker? Your immune system will fight tooth and nail against life-saving organ transplants but then completely ignore that cancer cell that's clearly up to no good. It's the biological equivalent of focusing on a typo while the building is on fire! 🔬💥
