"我的痛苦可能是别人笑的理由。但我的笑声绝不能成为别人痛苦的原因。"

Simplified Meaning:

Sometimes, people might laugh because of someone's problems or suffering, but it's important that our own happiness never causes others to feel hurt or sad. For example, if someone slips and falls, it might make others laugh, but when you yourself are happy and laughing, it shouldn’t be because you made fun of someone or hurt their feelings. In history, comedians often make jokes about difficult situations, like Charlie Chaplin who brought humor during tough times, but they aim to make people laugh in a way that everyone feels good. If you’re joking with friends, always make sure no one is the target of a mean joke, as this could hurt their feelings. So, we should be thoughtful and kind, enjoying our happiness without causing distress to someone else. This can be applied in everyday interactions by being considerate when teasing or joking, ensuring it's in good spirit and doesn't harm anyone. This way, laughter and happiness can be shared, not used as a tool to belittle others.
