One day, whilst we were still upon the very best terms, he received me so coldly and in a manner so different from that which was customary to him, that after having given him an opportunity to explain, and even having begged him to do it, I left his house with a resolution, in which I have persevered, never to return to it again; for I am seldom seen where I have been once ill received, and in this case there was no Diderot who pleaded for M. de Joinville. I vainly endeavored to discover what I had done to offend him; I could not recollect a circumstance at which he could possibly have taken offence. I was certain of never having spoken of him or his in any other than in the most honorable manner; for he had acquired my friendship, and besides my having nothing but favorable things to say of him, my most inviolable maxim has been that of never speaking but in an honorable manner of the houses I frequented.
At length, by continually ruminating. I formed the following conjecture: the last time we had seen each other, I had supped with him at the apartment of some girls of his acquaintance, in company with two or three clerks in the office of foreign affairs, very amiable men, and who had neither the manner nor appearance of libertines; and on my part, I can assert that the whole evening passed in making melancholy reflections on the wretched fate of the creatures with whom we were. I did not pay anything, as M. de Joinville gave the supper, nor did I make the girls the least present, because I gave them not the opportunity I had done to the padoana of establishing a claim to the trifle I might have offered, We all came away together, cheerfully and upon very good terms. Without having made a second visit to the girls, I went three or four days afterwards to dine with M. de Joinville, whom I had not seen during that interval, and who gave me the reception of which I have spoken. Unable to suppose any other cause for it than some misunderstanding relative to the supper, and perceiving he had no inclination to explain, I resolved to visit him no longer, but I still continued to send him my works: he frequently sent me his compliments, and one evening, meeting him in the green-room of the French theatre, he obligingly reproached me with not having called to see him, which, however, did not induce me to depart from my resolution. Therefore this affair had rather the appearance of a coolness than a rupture. However, not having heard of nor seen him since that time, it would have been too late after an absence of several years, to renew my acquaintance with him. It is for this reason M. de Joinville is not named in my list, although I had for a considerable time frequented his house.
