Oh, I think you might be talking about 'cyber etiquette' or 'netiquette'! It's kind of like good manners, but for the internet. Just like we use please and thank you when we talk to people in person, we need to be polite and kind when we're using the internet.
For example, if you're chatting with someone online, it's important to use friendly words and manners, just like you would if you were talking face-to-face. It's also important to be careful about sharing personal information or photos with people you don't know well, because just like in real life, we need to be cautious about who we trust.
Another important part of internet etiquette is being respectful to others' ideas and opinions. We should never be mean or bully someone online, and we should always remember that there are real people with real feelings on the other side of the screen.
So, just like we learned how to behave nicely in the real world, we need to learn how to behave nicely in the online world too. It's all about being kind, using good manners, and staying safe.
