How to Answer WHATS UP in English What Americans REALLY mean SHORTS

A common greeting in the US is “What’s up?”
But if English isn’t your native language,  

you might think, “I don’t know, the ceiling fan?”
You know what? When people ask this question  

they’re not literally asking what’s up and they’re 
not even asking how we use it idiomatically  

which is to say “What’s going on with you?”
It’s just another way to say hi. They are literally  

just saying hi when they say “What’s up?”
So, how do you respond to  

the question “What’s up?”
The most common easiest answer, the one that’s  

most expected is “Nothing” or “Not much”.
What’s up with you? 

So say nothing or not much and then return the 
question, that is generally how we respond to this greeting.
