Okay kiddo, let me explain Japanese pronouns to you! In Japanese, people often use different words instead of saying "I," "you," or "he/she."
For example, Japanese people use "watashi" to mean "I" most of the time. But they can also use "boku" if they are a boy or "atashi" if they are a girl. Sometimes they might use "ore" if they are in a more casual setting or if they are talking with friends.
Now, for "you," Japanese people use "anata" most of the time. But if they are talking to someone younger than them, they might use "kimi" instead. And if they are talking to someone very close to them, like a family member or a close friend, they might just use their name instead of a pronoun.
For "he" or "she," Japanese people use "kare" or "kanojo." But sometimes they might use the person's name instead. And if they are talking about someone who is older or someone they respect, they might use "sensei" instead of a pronoun.
So, basically, Japanese people use different words depending on who they are talking to and how formal or casual the situation is. It might seem a bit confusing at first, but with practice, it becomes easier to understand!
