American Expression Post
In America, we often use the expression

“I hear you” to say that you understand someone or you agree with what they say, it depends on context.
Agreement:
“I hate waking up early.”
“Yeah, I hear you. I like to wake up late.”

“I love California.”
“I hear you, I love the beach.”


Understanding:
“I think that this is the right way to do it.”
“I hear you, but I don’t think so.”

“Like I was saying, I think that dogs are better than cats.”
“Yeah, I hear you, but I think that cats are way better.”

This is used in more casual speech, typically between friends and family. However, it wouldn’t necessarily be rude to use it in a formal situation, it’s just not as common.

I hope that this helps you and if you have any questions, please feel free to ask me :)
