When we talk to different people, we use different words and expressions to show respect and politeness. In Japan, they have a special way of speaking called "honorific speech" or "keigo."
When Japanese people talk to someone older or in a higher position, they use different words and expressions to show respect. They can also do this when talking about someone else who is in a higher position or a respected person.
For example, instead of saying "you" (anata) like we do in English, they might use "sensei" (teacher) or "san" (Mr./Mrs./Ms.) when talking to someone older or in a higher position. They might also use more formal language and add polite expressions like "arigatou gozaimasu" (thank you very much).
On the other hand, when talking to someone younger or in a lower position, they might use more casual language and even add some friendly expressions like "doumo" (thanks) or "yoroshiku" (please).
Overall, honorific speech is an important part of Japanese culture and shows respect and politeness towards others. By using the right words and expressions, they can create a polite and respectful conversation.
