Tory (the Respiratory System) was on his evening run, as he does everyday to stay healthy. He bumped into Nero (Nervous system). "Hola niño 🌝." he said. He knew very well that they were the same age, but he liked to call him niño because hes been helping him live and breathe (Tory's main function) for so long that at this point he is a child to him. "Hola." Nero replied.
