Murphy asked a good question because Ram also wanted to know why Number Thirteen kept hitting Murphy's bald head.
Number Thirteen fell into deep thought, and after pondering for a long time, he said calmly, "No reason. I don't want to kill you, after all, you are my friend, but I can't let you go either. If you insist on foolish ideas, then I'll have no choice but to kill you. Until I figure out a solution, I'll just have to hit you to alleviate the bitterness and anger in my heart, you know, I usually don't get angry easily, and even when I do, I don't show it."
Murphy, with a dumbfounded expression, said, "If you're going to hit me, just hit me, why do you have to hit my head?"
"Hmm..."
This time Number Thirteen didn't take long to think. He said seriously: "Your head is very shiny, and it feels good to hit."
Murphy's eyes widened and then he said slowly to Number Thirteen, "Fuck You!"
Number Thirteen shrugged and slapped him again.
