Dinner Thank-You Note
Even an invitation to dinner can merit a personalized thank-you. When a dinner party is hosted by more than one individual, be sure to send a personalized thank-you to all hosts. For an event hosted by an organization, a thank-you letter should be sent to the chairperson and the board of directors. (This way you include the secretary/treasurer, vice president, and other officials of the organization.)

Dear Lara, Randy, and family,
Thank you for a truly delightful evening. I have to admit, when Lara first said that she was going to let the kids “build” their own pizzas, I thought she was asking for trouble — or at the very least, a very messy kitchen by the end of the evening. Instead, everything worked out well, the pizza was delicious, and the kids are still talking about how much fun they had. (Your kitchen seemed to survive, too!)
I was especially impressed by how well everything was organized. Having all of the toppings set out on the table where they were within reach of even the youngest child was evidence of that. Thanks to your well-thought-out plan, there wasn't a fussy eater in the bunch.
Thank you so much for inviting us to take part.
Fondly,
Laura, Mark, and family
A thank-you note is one place where extra adjectives are acceptable. Just keep in mind that your language needs to sound sincere, not overly dramatized. The amount of flowery language you use is determined by how familiar you are with the person to whom you're addressing your letter.
