I am very far from regretting the training, which my relations with Aunt Harriet and Uncle Edwin gave me, in what Roman Catholic casuists call 'economy' and 'reserve,' and some Protestants in their crude way call by a harsher name. Throughout life I have found it most useful to have learned to hold my tongue, to say less than I think, and to seem to agree more than I do, when in company of authoritative persons who have made up their minds and do not mean to alter them. I recommend all young men and women to acquire this art as soon as may be, and I wish them the luck to do so as early and with as little inconvenience as I did. Truth (even if one knew that one possessed it) is far too valuable a commodity to be lavished on the self-opinionated, and far too inflammatory a one to be uttered without due regard to persons and occasions.
