"I really don't understand, Grandpa, what exactly are you thinking? Can you still not tell the difference between lies now? Let me explain it to you this way, even if I told you something out of a kind lie, a benevolent deception, but it's still a lie, isn't it? Regardless of your intentions, telling lies to others is still lying. It's impossible for the nature to change the essence of a lie; it remains a lie regardless, why haven't you understood the fundamental aspect of this truth by now? At this point, you continue to make excuses and defend yourself repeatedly, do you think it's meaningful?"
