Responding to your well-meaning but condescending elderly mother's text can be done with grace and respect. Here's a suggested response that acknowledges her concern while expressing your preferences:
"Thank you, Mom, for your thoughtful response. I appreciate your concern. I just wanted to share that I'm not a big fan of [dish name], but don't worry, I'll find something else to enjoy at the dinner tomorrow. Looking forward to spending time with the family!"
This response conveys your gratitude for her care and consideration while still asserting your preferences. It's important to maintain a positive and respectful tone, as communication with loved ones is essential for maintaining strong relationships.
