Dear __________,
You always throw such wonderful parties! Thank you for inviting us over. You have so many fun and interesting friends, and it was a joy to have a chance to meet, mingle, and talk with them. And you really out did yourself with the buffet table. What a spread! So many incredible gourmet appetizers and desserts, and the port was simply scrumptious. We really enjoyed ourselves last night, and we’re thankful for your friendship.
