When someone says, "mention not," they are typically using a polite expression to let you know that you don't need to thank them or express gratitude for something they did. In other words, they are saying that what they did for you was not a big deal and there's no need to mention or acknowledge it.
If someone says "mention not" in response to your thank you or gratitude, you can simply accept their gesture with a smile and perhaps respond with a polite acknowledgment. Here are some appropriate responses:
- "Thank you, I appreciate your help/kindness/thoughtfulness."
- "Thanks again for your assistance, it was really helpful."
- "I'm grateful for what you did, thank you."
- "I'm glad you could help, thanks!"
Remember to maintain a positive and appreciative tone in your response, even if they insist that it was not necessary. Showing gratitude and acknowledging their efforts can help reinforce a positive interaction and maintain good relations with the person.
