Is it OK to say 貴方 when there is no other option. I'm still pretty new to Japanese, and I was wondering if there are moments when it is okay to say 貴方. I know that it's often better to address someone by their name or just imply that they are the topic. So, what if I don't know somebody's name and I cannot imply them as the topic of what I want to say? Are there times when I must say 貴方 for the sentence to make sense, or is it possible to imply it every-time? If there are cases when you must say 貴方, can you give examples with English translations?
