I received, my dear friend, your immensely kind letter, and ever since I have done nothing but think of that charming project of spending a few days in Sannois with you. There is nothing I would like better than to do so, but the more I think about it, the less feasible it seems, for I am less able to walk than the last time I had the pleasure of seeing you. Going no further than Madame Brillon's caused me to be in pain for several days. I am thus obliged to give up the pleasure that awaited me in your pleasant company at your charming Sannois retreat and to console myself with the hope of seeing you a few times when you return to Paris. My grandsons are very touched that you remembered them and invited them to come with me. They add their sincere thanks to my own. May you have good health and good cheer during your trip and find everywhere the happiness that you will bring to your friends.
