When someone asks you "How are you?", you can respond in several ways depending on how you feel and how well you know the person asking. Here are some common replies: 1. If you're feeling good: "I'm doing well, thank you! How about you?" 2. If you're feeling okay: "I'm doing alright, thanks for asking. How are you?" 3. If you're not feeling well: "I've been better, but I'll manage. How are you?" 4. If you don't want to share your feelings: "I'm hanging in there, thanks. How about you?" Remember to ask the person how they are doing in return, as it shows that you also care about their well-being.
