Summarize a Ben Franklin anecdote and tell what character trait he is demonstrating

Benjamin Franklin begins writing Part One of his Autobiography in 1771 at the age of 65 while on a country vacation in England in the town of Twyford. In the opening pages, he addresses his son, William, the Royal Governor of New Jersey, telling him that he, Benjamin, has always taken pleasure in hearing stories about his family members, and suggesting that William might enjoy hearing the story of his father's life. It is the perfect time for him to set his life to paper because he has a period of leisure.

It is important to note that Franklin, in this first part of his Autobiography, at least claims that he is writing for his son and family, and not for the public at large. This position of Franklin's changes, and so does the tone and style of Franklin's writing, in later sections of the Autobiography where Franklin's stated audience changes to a larger public.
