Mozart's love for his father made him dependent on the latter to the end of his days. He was a model son and must have loved his wife devotedly, since, for her sake, he once in his life disobeyed his father. The majority of his letters which have been preserved are addressed to his father, to whom he reported all his happenings and whose advice he is forever seeking. Similar were his relations with his sister Marianne (Nannerl), whom he loved with great tenderness. The letters to his wife are unique; all of them, even the last, seem to be the letters of a lover. They were a pair of turtle-doves.

Mozart was an ideal friend, ready to sacrifice to the uttermost on the altar of friendship. It was this trait of character which made him throw himself with enthusiasm into Freemasonry, whose affiliations he sought to widen by drafting the constitution of a community which he called "The Grotto." He probably hated only one man in the world,—the Archbishop of Salzburg, his tormentor.

185. "The moment you do not trust me I shall distrust myself. The time is past, it is true, when I used to stand on the settle, sing oragna fiagata fa and kiss the tip end of your nose; but have I therefore shown laxity in respect, love and obedience? I say no more."

(Mannheim, February 19, 1779, to his father, who was vexed because Mozart was showing a disposition to stay in Mannheim, because of a love affair, instead of going to Paris. "Off with you to Paris, and soon!" wrote the father. The Italian words are meaningless and but a bit of child's play, the nature of which can be gathered from Mozart's remark.)

186. "Pray do not let your mind often harbor the thought that I shall ever forget you! It is intolerable to me. My chief aim in life has been, is, and will be to strive so that we may soon be reunited and happy….Reflect that you have a son who will never consciously forget his filial duty toward you, and who will labor ever to grow more worthy of so good a father."

(Mannheim, February 28, 1778, to his father.)

187. "The first thing I did after reading your letter was to go on my knees, and, out of a full heart, thank my dear God for this mercy. Now I am again at peace, since I know that I need no longer be concerned about the two persons who are the dearest things on earth to me."

(Paris, July 31, 1778, to his father, who had written that he and
Nannerl had comforted each other on the death of his mother.)

188. "Dearest, best of fathers! I wish you all conceivable good; whatever can be wished, that I wish you,—but no, I wish you nothing, but myself everything. For myself, then, I wish that you remain well and live innumerable years to my great happiness and pleasure; I wish that everything that I undertake may agree with your desire and liking,—or, rather, that I may undertake nothing which might not turn out to your joy. This also I hope, for whatever adds to the happiness of your son must naturally be agreeable also to you."

(Vienna, November 16, 1781, to his father, congratulating him on his name-day. On March 17, 1778, Mozart had written from Mannheim: "Your accuracy extends to all things. 'Papa comes directly after God' was my maxim as a child and I shall stick to it.")
