Sometimes when i see the movies
They usually say "you"

But it's kinda weird to me
because they dont meant to say "You"

For example

A: How's the test? What grades did you get?
B: i just passed. they dont have any grades,
"If you get above the average, you're just pass"

There was no expression "YOU" in subtitles


I thought it was just a liberal translation,
but.. i dont think so
I think you guys usually use the word "you",
including when you dont need expression "you"


Am i right?

We use the word "you" in hypothetical situations. In English, we use words like "you", "he", "she" a lot more. We don't have the understanding of who we are talking to when we speak, instead we have to use pronouns.

For example, in Korean, you would just say " 이름이 뭐예요?", but in English, we have to say "What is /your/ name?", even if it is obvious who we are talking to.

We cannot speak without a subject, so when talking about hypothetical (not real or example) situations, we use "you."
Ex: You would say, "If you want to pass, you have to study hard."
or, "if you commit a crime, you'll go to jail."
or, "if you mess up, you'll get kicked out."
We say "you" even if we are talking about something that does not apply to someone.
