How to say "I'm fine, thank you. How about you?" in Korean. (And some more question) In need for help >< I recently received an email from my teacher who moved back to Korea.. She sent me "잘지내죠?" Is it correct for me to reply with "고맙습니다. 전 지내요, 선생님은요?" ? And she added "친구도 잘 지내는지 궁금해요" I see the friend word.. But I have no idea what does the rest mean >< I'm assuming that she asked how are my friends? And she added "건강하세용" too.. Is there any difference between "건강하세요" and "건강하세용"? And is it right for me to reply with "건강 유지~ 또는 학생 걱정합니다.." ? (Stay healthy. Your students will be worried if you're sick) ? Thanks in advance for your help :)
