Dear __________,
What a fun time we all had last night, laughing, dancing, eating, and drinking, until the wee hours of the morning! And there was no land-lord upstairs telling us to quiet it down! It was great that you and Veronica could make it to our house-warming party. And thank you so much for your thoughtful gift of a music CD from my favorite artist. Now that Mike and I have our own place, we plan to host several gatherings and BBQs in the months and years ahead, and you will always remain at the top of the guest list!
