Dear _________,
Thank you for inviting us to your beautiful home for dinner. Everything was so delicious. Your homemade ravioli and pesto pasta were incredible. And the red wine you served was outstanding. We always have such a wonderful time whenever we get together with you. I only wish we lived closer. Bob and I are still laughing at that vacation story you shared with us. You two are so much fun! Thank you again for a fabulous evening.
