So, you've probably heard adults use the word "you" a lot. Sometimes they might say things like "you should do your homework" or "you need to eat your vegetables." But did you know that sometimes when they say "you," they don't actually mean you specifically?
They are using something called "generic you." It's like a pretend person that they are talking to, but it's not really anyone in particular. They use it to talk about things that are true for a lot of people, but they don't want to make it sound like they are telling you what to do.
For example, if a teacher says "you should always try your best," they don't necessarily mean that you, specifically, never try your best. They are just giving you some advice that is true for most people.
It might seem a little confusing, but just remember that when people use "you" like this, they are not talking directly to you. They are just using it as a way to make a general statement.
