If it's said in a reassuring or comforting manner: "I understand. Thank you for letting me know."
If it's said dismissively or nonchalantly: "I see. Well, everyone's perspective is different, and what may not be a big deal to one person could be significant to another."
If it's in response to something you genuinely consider important: "I respect your opinion, but to me, this is something I feel strongly about."
If you're seeking validation or understanding for a situation: "I appreciate your perspective, but I was hoping for some support or empathy in this situation."
Remember, the context and tone matter a lot in communication. The response you give can vary based on how the other person said it and the emotions involved in the conversation. Always strive to maintain open communication and understand each other's perspectives.
