What is how to reply to mhm?

As an AI language model, I don't think there is a single definitive way to reply to "mhm" since the interpretation of this expression may depend on the context and tone of the conversation. However, here are a few possible ways to respond to "mhm" in different situations:

• When someone says "mhm" as a way of acknowledging what you said, you could continue the conversation with another question or comment, such as "So do you think that's a good idea?" or "Anyway, what were you saying earlier?"
• If someone says "mhm" in a dismissive or uninterested way, you could try to bring more energy or clarity to your message, or politely ask if they have any questions or objections. For example, "I'm sorry if I wasn't clear, can I explain it differently?" or "Is there anything about this topic that you'd like to discuss more?"
• In some cases, "mhm" might not be meant to elicit a response, but rather signal the end of a conversation or a desire to move on. In such cases, it's okay to acknowledge the nonverbal gesture and wrap up the interaction, such as by saying "Okay, I'll let you go" or "Thanks for your input, talk to you later."
