You say something but the person had misunderstood (big time) and goes "WHAT DID YOU SAY?!"

만약 그쪽 잘못 알아들었다... (Did I spell that right?)

Before the person starts to boil, quickly (열받기전에 빨리) start with, "No, no, no..." and then say:

"That is not what I meant."
"You have misunderstood me."
"There has been a misunderstanding."

그리고...

(다시한번)
"Let me rephrase that."
"What I meant to say was..."

I often hear Koreans say:

"You don't know what I am saying." or even "You don't know."
"You don't hear me."
"You hear me wrong." or even "You are wrong!"

They might work, but the tone above (분위기? 말투?) may be a little rude (싸가지! ) and may make matters worse.


A little message to English speakers:

Give these guys a break. They're just trying their best to communicate; gotta give them a little respect for their effort. If something sounds a little weird to you, give them the benefit of the doubt. It's not their native language and believe it or not, English is a pretty difficult language.

And I beg everyone...don't do that sarcastic, loud and slow English thing to them...I think some of you all know what I mean. That's really cruel (humiliating someone for their lack of knowledge in public).
