Okay, so this goes back to the whole "finding the right word for 'you' in Korean," but I need some help. I'm potentially going to be tutoring a Korean student, and I've talked with her mother before (in Korean) - but I haven't known how to address the mother (eg. "how about you?"). If it helps clarify the situation, she's likely about 20 years older than me.
If someone could help me with this...
