When I first started learning English as my second language, I was taught that when you greet someone you can say stuff like:
"Hey, how are you [doing]?"
and the normal response would be:
"I'm doing alright (or pretty much any sentence with the same meaning). What about you?"
However, in practice, I found out that people tend to use phrases like,
"Hey, you Okay?" or "Hey, you alright?"
and I'm not sure what the proper response would be. I usually find myself saying something like, "I'm alright. Thanks" (I figured, saying "I'm alright. How about you?" wasn't really the proper response). But I feel like, by saying that, I'm being inconsiderate (I feel like I have to ask them how they're doing). What are some good responses that also ask about the listener as well?
