When someone says "you say?" in response to something you've said, they are likely seeking clarification or asking you to elaborate on your previous statement. In this situation, you can respond in several ways, depending on the context and what was said before. Here are some possible ways to reply:
Elaborate on your previous statement: You can provide more details or examples to make your point clearer. Example: "What I meant was [add more context or explanation]..."
Reiterate your main point: Restate your original statement in a different way to ensure understanding. Example: "In essence, I'm saying that [summarize your main idea]."
Ask for clarification: If you're unsure what part of your statement they are referring to, you can seek clarification. Example: "Sure, could you let me know what specifically you would like to know more about?"
Check if they agree or disagree: You can gauge their reaction and see if they have a different perspective on what you said. Example: "Do you agree with my point, or do you have a different view on this?"
Seek feedback: You can ask for their opinion on what you said. Example: "What are your thoughts on this?"
Address any confusion: If there was a misunderstanding, you can clarify or correct it. Example: "I might have misspoke; let me rephrase that..."
Remember to maintain an open and respectful communication style while responding. It's essential to engage in a constructive dialogue and be receptive to others' viewpoints as well.
