At Braintree his mother watched over his childhood. At the village school he learned the rudiments of the English language. In after life he often playfully boasted that the dame who taught him to spell flattered him into learning his letters by telling him he would prove a scholar. The notes and habits of the birds and wild animals of the vicinity early excited his attention, and led him to look on nature with a lover's eye, creating an attachment to the home of his childhood, which time strengthened. Many years afterwards, when residing in Europe, he wrote: "Penn's Hill and Braintree North Common Rocks never looked and never felt to me like any other hill or any other rocks; because every rock and every pebble upon them associates itself with the first consciousness of my existence. If there is a Bostonian who ever sailed from his own harbor for distant lands, or returned to it from them, without feelings, at the sight of the Blue Hills, which he is unable to express, his heart is differently constituted from mine." These local attachments were indissolubly associated with the events of the American Revolution, and with the patriotic principles instilled by his mother. Standing with her on the summit of Penn's Hill, he heard the cannon booming from the battle of Bunker's Hill, and saw the smoke and flames of burning Charlestown. During the siege of Boston he often climbed the same eminence alone, to watch the shells and rockets thrown by the American army. With a mind prematurely developed and cultivated by the influence of the characters of his parents and the stirring events of that period, he embarked, at the age of eleven years, in February, 1778, from the shore of his native town, with his father, in a small boat, which conveyed them to a ship in Nantasket Roads, bound for Europe. John Adams had been associated in a commission with Benjamin Franklin and Arthur Lee, as plenipotentiary to the Court of France. After residing in Paris until June, 1779, he returned to America, accompanied by his son. Being immediately appointed, by Congress, minister plenipotentiary to negotiate a treaty of peace and commerce with Great Britain, they both returned together to France in November, taking passage in a French frigate. On this his second voyage to Europe, young Adams began a diary, which, with few intermissions, he continued through life. While in Paris he resumed the study of the ancient and modern languages, which had been interrupted by his return to America.
